8 September Sales and Deals You Can't Miss (Plus 4 You Can)

September sales aren't as flashy as the sales coming up in October and November (like Prime Big Deal Days and Black Friday sales), but that doesn't mean you can't get some incredible deals. September is a good time to stock up on things like German food at Aldi during Aldi German Week, baby gear at Walmart and Target, and even some early Halloween deals.

We also see Labor Day sales early in the month; you'll find outdoor clearance sales happening through October, with patio clearance prices up to 70% off. And you can stack a 20% off Target student discount on top of any back-to-school clearance deals that are still available through Sept. 27.

Don't sleep on the September food holidays and freebies either. National Cheeseburger Day, National Coffee Day, and free admission to parks and museums mean you can wrap up the summer without overspending. Here's everything you need to know about what's happening in September, from sales to freebies.

What to Buy in September

Outdoor Clearance

Retailers don’t want to store bulky seasonal inventory over winter, so they discount outdoor items hard right after Labor Day. Look for the best deals in early to mid-September. You'll find the best deals at Walmart, Home Depot, Lowe's, and Wayfair.

Patio Furniture

Since outdoor living season is over in most regions, demand drops sharply, which means prices drop by 50% - 70%. The earlier in the month you shop, the better the selection; by October, inventory becomes very limited.

Grills

Stores can't store bulky grills and smokers over the winter, so they slash prices pretty aggressively, up to 50% off or more. Watch for the biggest cuts on floor models and last season’s designs. September is also when you’ll see bundle deals, like free propane tanks or grilling accessories with a grill purchase.

Lawn Care and Gardening Supplies

Expect discounts of 40% - 70% on everything from annual flowers to lawnmowers. Some of the biggest price drops will be on plants, soil, mulch, seeds, planters, and lawn care tools. Stock up in September for next season.

Bikes, Sports Gear, and Camping Equipment

You can often find 40% - 60% off bikes, helmets, scooters, and skateboards, as well as tents, sleeping bags, and portable grills. Shop stores like REI Co-op, Backcountry, and Amazon for the lowest prices this month.

Mattresses and Bedding

If you missed Memorial Day deals, September is your next best shot at mattress and bedding savings. Discounts will be at 20% - 40%, with savings up to $600 on premium brands like Tempur-Pedic. Also watch for bonus deals like free pillows or mattress protectors.

Baby Products

The semi-annual Walmart Baby Days event and the Target Baby Sale typically return every September. You'll find deals on brands like Evenflo, Safety 1st, Jeep, and more.

And the Target Car Seat Trade-In event usually runs in tandem with the baby sale. So you’ll also get a 20% off coupon if you trade in your old car seat. 

(Last-Minute) College Essentials

If you’re going through your first week of classes making a mental list of all the things you still need for the fall semester, you can score 20% off with the Target College Student Discount, which ends Sept. 27, 2025.

You can absolutely stack this discount on top of other Target Circle deals. Just be sure to join Target Circle if you haven’t already and upload a valid student ID, class schedule, or a recent tuition receipt to get the discount. 

German Foods at Aldi

Aldi’s German Week is predicted to arrive mid-month on Sept. 17. During German Week, you can expect deals on the Deutsche Küche brand, with prices starting as low as $1.39. Stock up in September on pork schnitzel, herring fillets, hazelnut biscuits, and egg spaetzle. 

Beauty Products

Two major beauty sales kicked off in late August, but run through half of September. Ulta 21 Days of Beauty and Sephora One-Day Deals both continue through Sept. 18. Deals change out every day of both sales, so be sure to check back regularly. Ulta also runs Weekly Steals, deals that run the whole week. These sales are both good chances to save on beauty brands that don't go on sale often, like Drunk Elephant, Tarte, and Sunday Riley.

Fall Travel

The Southwest Wanna Get Away Sale offers one-way fares starting at just $39. The September sale is a great chance for travelers to get discounted flights during the fall season. Plus, Southwest features additional deals and offers to help customers save on various other travel expenses like hotels and rental cars.

Halloween Items (At Certain Stores)

You don’t have to wait for after the holiday to score Halloween deals. Shop early in September, and you’ll see costumes for as low as $5 at Walmart, for example. If you're interested in some of these early deals, don't wait to shop. They won’t last until Halloween clearance time, and they’re already at a super low price. (However, there will definitely be more Halloween clearance in November. Last year, Lowe’s offered a Halloween clearance sale with items up to 75% off.)

Plus, Starbucks releases their Halloween cups on Sept. 16, and those almost always sell out.

September Calendar Reminders

National Cheese Pizza Day: Sept. 5

Every year, National Cheese Pizza Day takes place on Sept. 5. In celebration, places like Pizza Hut, Chuck E. Cheese, and Little Caesars offer BOGOs and discounts.

$0.85 Blizzards at DQ: Sept. 8 - 21

Dairy Queen's $0.85 Blizzard promotion is a nostalgic nod to the year 1985, when the iconic Blizzard Treat was first introduced. This special offer allows customers to enjoy a small Blizzard for just $0.85 (with a purchase of at least $1), typically available for a limited time through the Dairy Queen Rewards mobile app.

Bank of America Free Museum Admission: Sept. 6 - 7

If you’re a Bank of America customer, you'll get free museum admission on Sept. 6 - 7 through the Museums on Us program. On the first full weekend of every month, Bank of America, Merrill, or Bank of America Private Bank (U.S. Trust) cardholders can gain free admission to over 225 museums across the United States.

Lowe’s Free Fall Flower Giveaway: Sept. 12

We predict a new Lowe's Fall Flower Giveaway on Sept. 12 - 13, 2025, and you'll just need to have a myLowe's Rewards account (it's free to sign up) and reserve your free fall-blooming flower in advance. The free fall flowering plants will likely run out quickly, so we recommend reserving your flower online ASAP.

National Cheeseburger Day: Sept. 18

On National Cheeseburger Day, we often see burger deals at Applebee's, Burger King, Smashburger, and more. Watch for deals like a free cheeseburger with any $1 purchase at Burger King, $0.01 burgers with any purchase at Wendy’s, and $0.50 double cheeseburgers at McDonald’s.

Free National Park Admission: Sept. 28

A few times a year, the U.S. Department of the Interior makes it free for everyone to enter the National Parks. The National Park Service has seven days you’ll get free park admission in 2025, and the next free day is Sept. 27, when you’ll be able to enter any of the U.S. National Parks without fees.

National Coffee Day: Sept. 29

Get free and discounted coffee on National Coffee Day. Last year, we saw free coffee from Dunkin’, 7-Eleven, Biggby, and more.
