Whether your family runs through one trash bag per week or one trash bag per day, there’s money you’re probably leaving on the table if you don’t know exactly how to save on garbage bags. Wanna learn?

The most important factor to consider is your cost per trash bag. After crunching the numbers on several brands and retailers, I found that the ideal cost per bag should be $0.12 or less. Not surprisingly, that’s way cheaper than the everyday prices we see on top brands like Glad and Hefty.

Below, I’ll break down exactly how to save money on garbage bags, including a comparison of each brand’s cost per bag, where to buy each, and everything you need to know about recycling and biodegradable trash bags. Once you figure out which trash bags you want to use, remember to download the Krazy Coupon Lady app and set alerts for name brands.


1. To find the cheap trash bags, start by calculating the price per bag.

close up on box of trash bags says 130 bags

Calculating your cost per trash bag is easy, as long as you can block out all of the extra info that brands and retailers throw at you. Simply take the cost of the box and divide that price by the total number of bags.

A $15 box divided by 100 bags = $0.15 per bag.

Breaking down your purchase by cost per bag makes cross-brand comparisons easy. And when we go over the top 9 brands in the U.S. in just a minute, all of which are well-reviewed, you’ll be able to make an educated choice on whether you want to switch from the brand you’re using to something new.


2. The goal is $0.12 or less per standard kitchen trash bag.

The two big names in trash bags are Glad and Hefty. Each brand usually sells 13-gallon kitchen bags for $0.20 or more at your local supermarket or a few pennies less at big box stores like Target and Walmart. But I’ll teach you how to leverage promotions and sales to get the big brands for less.

And, I discovered while researching this topic that the key to paying just $0.12 is looking outside the two big names.

By shopping well-reviewed store brands or waiting for the perfect sale to come along then stocking up on the big name brands, you can absolutely meet the goal of paying no more than $0.12 per trash bag. And you may be able to do substantially better.


3. Here’s the average cost per trash bag, by brand:

In this article, we’re exclusively studying cost on standard 13-gallon kitchen trash bags, the most popular garbage bag size in the U.S.


Sam’s Club trash bags

graphic showing Sam's Club trash bags for $0.09 average cost per sq ft

Sam’s Club garbage bags top our list with the best everyday value on the market.

  • Member’s Mark 13-gallon Power Flex Kitchen Trash Bags, 200 count cost $18.48 ($0.09 per bag) here.

The savings on trash bags alone could very well justify the cost of a $45 a year Sam’s Club membership. Learn how to get a free membership.

But, remember if you’re not a member, you can still shop Sam’s and pay an extra 10% “handling fee” for every purchase. Even with that fee, the average price per bag only goes up to $0.10 — that’s still tied for the best value on this list. Choose curbside pickup if you can. That way you’ll dodge their $5 shipping fee.

As if the price isn’t already good enough, Sam’s Club is still actively offering Instant Savings a few times a year that will get you another dollar off the price.

Home Depot trash bags

graphic showing Home Depot trash bags for $0.10 average cost per sq ft

Home Depot’s brand, HDX was a surprise contender for best place on trash bags. HDX makes two types of bags. The normal “Flex” bags have poor reviews so we skipped them in this article, but the FlexPro reviews are great.

There’s a strategy you’ll have to use when buying Home Depot trash bags, if you want the best price. You have to stock up. If you buy only one box at a time, you’re leaving money on the table because buying two will drop your cost per bag significantly. And the multi-buy discount is exclusively online. Select store pickup for a quick, no-cost option. Or, shipping is free to your house on orders over $45.

  • HDX 13-gallon FlexPro Kitchen Trash Bag, 140 count cost $18.47 ($0.13 per bag) here.
  • HDX 13-gallon FlexPro Kitchen Trash Bag, 280 count cost $27.94 ($0.10 per bag) here.
  • HDX 13-gallon FlexPro Kitchen Trash Bag, 600 count cost $55.88 ($0.09 per bag) here. (Plus, will qualify for free shipping.)

In my book, at under ten cents per bag, that’s a deal worth stocking up on. And even though HDX trash bags are sold in-stores, this multi-buy deal is only available online.

Amazon trash bags

graphic showing Amazon trash bags for $0.11 average cost per sq ft

Amazon’s Solimo trash bags are what I have under my kitchen sink. I’ve been paying $0.11 per bag, not knowing I could do better. The bags have near 100,000 great reviews and I can add my own to the pile. I’ve never had a single problem with Amazon garbage bags.

When aiming for that eleven cent per bag price, you get to choose whether to buy a smaller box and leverage the 15% Subscribe & Save discount, or just go with the bigger box to begin with.

  • Solimo 13-gallon Kitchen Trash Bags 120 count cost $15.36 ($0.13 per bag, $0.11 with Subscribe & Save) here.
  • Solimo 13-gallon Kitchen Trash Bags, 200 count cost $22.03 ($0.11 per bag) here.

Since Solimo is an Amazon exclusive, there’s no shopping around to save you money. If you don’t know already, here’s how Amazon Subscribe & Save works. It’s the single greatest tool for shopping Amazon.

You’ll save 15% ($0.02 per bag) when you subscribe to any five items in the same month. Here is a list of our best Subscribe & Save deals so you can find others to add along with your trash bags. And yes, if you have the room, you could just subscribe to 5 boxes of trash bags at once to get that 15% discount. Remember you can cancel Subscribe & Save any time, including after your first shipment.

Costco trash bags

graphic showing Costco trash bags for $0.11 average cost per sq ft

It was difficult to rank Costco trash bag prices because they frequently have higher prices online and cheaper prices in stores.

In fact, the $0.11 per bag is the online price. At my local Costco, the 200-count box sells for $18.99 instead of $22.49 online, which drops the price to $0.095 per bag and puts Costco trash bags nearly in-line with Sam’s Club trash bags.

For me, the podium is clear: Sam’s Club, Costco and Home Depot are the three best places to buy trash bags. Sam’s Club gets the gold. Costco may have a better argument than Home Depot for the silver. Home Depot is great if you want to shop online. Costco is better if you want to shop in store.

  • Kirkland Signature 13-gallon Flex-Tech Kitchen Trash Bag, 200 count cost $22.49 ($0.11 per bag) here.
  • Kirkland Signature 13-gallon Flex-Tech Kitchen Trash Bag, 200 count cost $22.49 ($0.095 per bag) in store only.

Prior to COVID-19 pandemic in 2020, we used to see Instant Savings of $2-3 per box a few times a year. Back then, the regular price per box was cheaper too. When those Instant Savings return, Costco will catapult to the best place to buy, during the instant savings period.

A Costco membership costs $60 per year, but non-members can shop Costco or Costco.com with a gift card. Get any member to purchase you a gift card and you can take advantage of Costco’s prices any day.

Lowe’s trash bags

graphic showing Lowe's trash bags for $0.12 average cost per sq ft

I seriously didn’t know about Home Depot and Lowe’s trash bags until writing this article. How cool is it that we have two new brands competing for your business and keeping the pricing low. Lowe’s isn’t as good as Home Depot but this is still a solid price, cheaper than either Target or Walmart brands.

  • MOXIE 13-gallon Kitchen Trash Bag, 130 count cost $15.98 ($0.12 per bag) here.

Lowe’s garbage bags’ price meets the $0.12 per bag stock price, but barely. But if you’re military or pro, you can use your Lowe’s discount to bring this price down to 11 cents flat.

Whatever you do, don’t buy a smaller pack of Moxie trash bags, like this 50-pack for $9.78 ($0.19 per bag). The value at Lowe’s gets significantly worse the fewer bags you buy, (the 40-pack runs you $0.32 per bag). “I don’t need more than forty trash bags” said no human ever.

Target trash bags

graphic showing Target trash bags for $0.13 average cost per sq ft

Even with your Target RedCard, the savings on Up & Up trash bags from Target don’t really stack up.

  • up & up 13-gallon FlexGuard Kitchen Trash Bags, 120 count cost $15.99 ($0.13 per bag) here.

RedCard would drop the price to $0.126 per bag, which is still above my stock-up price. There are coupons in the Target Circle section of the Target app but we don’t frequently see offers for up & up trash bags, so the price you see here is likely the best you’ll be able to get unless you get lucky with Target clearance.

Walmart trash bags

graphic showing Walmart trash bags for $0.14 average cost per sq ft

I was surprised to find Walmart trash bags actually have the highest cost per bag of any of the store brands I checked. Reviews for the Walmart’s bags are pretty good with a typical sprinkling of angry people calling the bags flimsy. Let’s not worry about reviews too much here because the price doesn’t cut it, so it’s a non-starter for that reason.

  • Great Value 13-gallon Kitchen Bags, 80 Count cost $11.33 ($0.14 per bag) here.

Walmart’s Great Value brand never has coupons, and we rarely see rollback prices, so $0.14 per bag is probably as good as it gets at Walmart, which is why I recommend you never buy your garbage bags there. Maybe Walmart is just conceding the victory to their big brother, Sam’s.

See this week’s biggest Walmart deals.


Hefty trash bags

graphic showing Hefty trash bags for $0.17 average cost per sq ft

Hefty garbage bags are actually only a fraction of a penny cheaper than Glad bags. But you’ll see that tiny difference on the shelf, especially if you’re at Target, where Glad bags are a bit overpriced so the difference between the two is widened.

Hefty kitchen bags typically sell for $0.17-0.18 at big box stores. Expect higher prices at supermarkets.

Unlike the store brands above, you have options with where to buy Hefty. Third place in the race is Target. Occasional gift card promotions like “buy 3, get a $10 gift card” can overlap with coupons in the Target app and create incredible deals, (some as low as $0.08 per bag) but that doesn’t happen very often.

Amazon gets second place. About twice a month, Amazon will run a promotion (often a match of those Target gift card promotions) plus you can save an additional 15% on top of the promo when you subscribe to a few boxes of trash bags at a time. When we see these deals, the price per bag is around $0.12.


Who has the best price on Hefty trash bags?

The best price on Hefty bags comes from Sam’s Club, where they cost just under $0.12 per bag every day.

  • Hefty Ultra Strong 13-Gallon Kitchen Drawstring Trash Bags, 150 count cost $17.68 ($0.12 per bag) here.
  • Hefty Ultra Strong 13-Gallon Kitchen Drawstring Trash Bags, 160 count cost $18.78 ($0.12 per bag) here.

A Sam’s Club membership costs $45 per year, (you can sometimes get a membership for free), but non-members can also shop at Sam’s Club and SamsClub.com and pay a 10% fee.


Where can I find coupons for Hefty trash bags?

Hefty releases coupons pretty regularly. Your best bets for finding Hefty coupons is to look in your store’s app. Kroger and Target have both had Hefty coupons every month or two.

Glad trash bags

graphic showing Glad trash bags for $0.18 average cost per sq ft

Glad trash bags are the most expensive supermarket brand in the U.S.

Sold everywhere, Glad bags frequently sell for over $0.20 per bag. Even Target’s shelf price is $0.19 per bag. Walmart is a little better at $0.177 per bag. And Amazon is even better — it gets second place in the rankings of best places to buy Glad garbage bags. At Amazon, Glad trash bags are often just $0.14-$0.15 each when you subscribe & save.

  • Glad ForceFlex 13-gallon Tall Kitchen Trash Bags, 110 count cost $18.64 ($0.17 each) or $15.84 ($0.14 each) with Subscribe & Save discount here.
  • Glad ForceFlex 13-gallon Tall Kitchen Trash Bags, 80 count cost $13.63 ($0.17 each) or $11.59 ($0.14 each) with Subscribe & Save discount here.


Who has the best price on Glad trash bags?

The best price on Glad bags comes from Sam’s Club, where Glad bags are just under $0.12 per bag every day.

  • Glad ForceFlex Tall Kitchen Trash Bags, 150 count $17.57 ($0.12 per bag) here.

A Sam’s Club membership costs $45 per year, (you can sometimes get a membership for free), but non-members can also shop at Sam’s Club and SamsClub.com and pay a 10% fee.


Where can I find coupons for Glad trash bags?

Glad trash bag coupons are extremely rare. Particularly since early 2020, there have been virtually no coupons available. Previous to the COVID-19 pandemic, Glad released coupons fairly regularly including some with values as high as $3 off one.

Today, the best Glad deals usually feature sales, subscription discounts and wholesale club instant savings. Download the Krazy Coupon Lady app and set alerts for Hefty or Glad, then you can just sit back and let us find those deals for you.

4. Trash bag deals are driven by promotions, not coupons.

someone holding target price tag for glad forceflex trash bag

As I stated above, there aren’t a lot of trash bag coupons out there, and trust me, our team here at KCL has looked. But that doesn’t mean there’s no savings angle. Promotions and sales are the key to saving finding great trash bag deals.

At Target, watch for promotions like “Buy 2, Get $5 gift card” or “Spend $50, get $10 gift card”. To calculate how much this saves you take the value of the gift card ($10) and divide by the spend ($50). In that example, you’re saving 20%.

At Amazon, watch for promotions that match what Target is running exactly. Target releases new promotions on Sundays and by Sunday afternoon, Amazon has matched them. And the best part? You can stack the Subscribe & Save discount with the promotion. You’ll just have to subscribe to multiple boxes of the same trash bag in order to stack both savings.

And don’t count out stores like Office Depot for sales and promotions too. Join the reward program here and watch for steep sale prices a few times a year that bring name brands like Glad to their lowest price anywhere.


5. This is one category where store brands are winning.

Member's Mark trash bag boxes stacked

I wasn’t expecting this conclusion when I started this article on trash bags. I figured that I’d teach you how to get name brands as cheaply, or even cheaper than store brands like I did in How to Save on Paper Towels.

I learned I was wrong. The trash bag game is dominated by incredible store brands. Sure, Member’s Mark is at the top of my list, but HDX, Kirkland and Moxie all impressed the heck outta me.

And given the reduction in sales and coupons on big name brands since pandemic times, I don’t see a compelling reason for brand loyalty in this category.


5. Buy the knockoff Simple Human trash bags.

someone pointing at plasticplace trash bag box next to box of simplehuman trash bag

I’ve nearly bought a sleek Simple Human trash can on dozens of occasions but I’ve yet to take the plunge. The trash cans aren’t cheap, but they’re nothing compared to the ongoing cost of the Simple Human trash bags. If you want to tempt yourself, these are the two best-selling trash can models:

  • simplehuman 13.2 gallon rectangular kitchen step trash can $129.99 here.
  • simplehuman 14.5 gallon rectangular hands-free kitchen step trash can with soft-close lid $179.99 here.

Simple Human charges upwards of $0.47 per bag for many of their trash bags. But really, you don’t have to use Simple Human trash bags just because you have a Simple Human trash can.

I’ve read Reddit threads where Simple Human trash can owners say they’ve successfully used any old trash bag. But if you’re a little nervous, PlasticPlace trash bags on Amazon are known to work well with Simple Human trash cans, and they cost as little as $0.14 per bag.

  • Plasticplace simplehuman compatible garbage liners, 12-13 gallon, 50 count $18.95 ($0.38 per bag) here.
  • Plasticplace simplehuman compatible garbage liners, 13 gallon, 200 Count $27.99 ($0.14 per bag) here.


6. Of all the trash bag sizes, 13-gallon kitchen bags are the most popular.

someone holding Solijmo trash bag box

Most families keep their largest trash can in the kitchen — the place where we create the most trash. 13-gallon trash bags are the most common size for most kitchen cans in the U.S.

Other garbage bag sizes for other rooms in the house include bathroom cans that are generally about 4 gallons and office trash cans are more like 7 gallons.

For the purposes of this article, we’ve been focusing exclusively on 13-gallon trash bags.


7. You can’t recycle trash bags unless they’re made for recycling.

someone holding Hefty trash bag box

Plastic trash bags are like any other plastic bag. Most standard curbside recycling bins don’t go to recycling centers that process plastic bags. And you can only recycle trash bags at a recycling center that processes plastic bags. In most places in the U.S., the best place to recycle plastic bags is a local supermarket. Find a location near you by visiting this website.

If you want to use trash bags for your recycle bin, you must buy a transparent bag made specifically for recycling. Using a regular white bag in the recycle bin could result in all your recyclables being sent to the landfill.

  • Hefty recycling trash bags, Blue, 13 Gallon, 60 Count cost $10.69 on Amazon ($0.18 per bag) here.


8. Biodegradable garbage bags in 13-gallon size can cost $0.50 per bag.

Unfortunately, if your priority is to lessen the environmental impact of consumption, switching to a 13-gallon compostable bag isn’t cheap.

  • Biobag compostable Bags 13 gallon, 12 count cost about $5.99 at my local Albertsons ($0.50 per bag)
  • Hefty compost bags 13 gallon, 12 count cost $12.99 on Amazon ($1.08 per bag) here.

I’ve tried using brown paper grocery bags — which were not a realistic solution in my household. My family decided that we were gonna keep using plastic trash bags but start composting as a way to offset our carbon footprint.

Now, I’m shopping for compost bags. Biodegradable trash bags typically come in a 2.5-3 gallon size and cost about $0.20 per bag. But the most affordable options are on Amazon, and if you use that same Subscribe & Save service that I mentioned earlier you can boost your savings by 15% by subscribing to five total products, making your per bag cost only about $0.16 cents.

  • BioBag compostable bag, 3 gallon, 100 count $19.31 ($0.19 per bag, $0.016 with subscription) here.
  • UNNI compostable bags, 2.6 gallon, 100 count $14.95 ($0.15 per bag) here.
