If you’re on the hunt for the best deals at Costco’s right now, let me give you a peek at a few of the hottest deals you shouldn't miss in March. All of these deals will stick around until March 31, 2024.
The best part about shopping these deals at Costco is that no physical coupons are required. For a longer list of all the Costco sale prices available month, check out our Costco Coupon Book post.
Of course, you're going to need to shop these deals in store to get the lowest possible prices (that's one of our favorite Costco price hacks). Why? Because Costco online shopping is always more expensive than in-warehouse shopping, even for members. And their online shopping gets even more costly if you order same-day delivery, which gets handled behind-the-scenes through Instacart.
Once you've browsed the best Costco deals right now, check out another little-known perk: Costco Next. It’s an online shopping platform with additional deals, and it’s only for Costco members.

Great Deals You'll Always Find at Costco
8. Pure Organic Maple Syrup
Buying pure organic maple syrup is always going to be more expensive than standard syrup, no matter where you shop. But you don’t need to spend an arm and a leg for the organic stuff. Coupons for pure organic maple syrup are few and far between, making deals very rare.
Bottom line? No other competitor comes close to Costco’s prices for organic syrup, so I always buy my pure organic maple syrup there. It’s 44% cheaper than Walmart’s price on organic maple syrup.
Costco: Kirkland Pure Organic Maple Syrup, 33.8 ounces, reg. price $12.99, or $0.35/ounce
Walmart: Maple Grove Farms Organic Maple Syrup, 8.5 ounces, reg. price $6.82, or $0.80/ounce
9. Cooked Costco Chickens
You're getting a better price for your chicken at Costco compared to Walmart, and you’ll even pay a little less if you buy them cold ($3.99).
Costco has made an effort to highly publicize their decision to keep chicken prices at $4.99, regardless of inflation. Costco has kept the price of their rotisserie chickens at $4.99 ever since 2009, even as competitor prices rise. The company even built a $450 million poultry complex in Nebraska to help keep their chicken prices so low.
Costco: Rotisserie Chicken, reg. price $4.99, or $1.66/pound
Walmart: Rotisserie Chicken, reg. price: $6.97, or $3.09/pound
10. Active Dry Yeast
I know what you’re thinking … who needs 32 ounces of yeast? When it’s 80% cheaper than what you can buy it for at Walmart, you can just keep it in the freezer to make it last longer ー up to six months!
Buying in bulk isn’t always the best option for everyone, but it’s definitely more cost-effective to go with Costco if you need a lot of yeast.
Costco: Red Star Active Dry Yeast, 32 ounces, reg. price $7.39, or $0.23/ounce
Walmart: Fleischmann’s Active Dry Yeast, 4-ounce, reg. price $5.48, or $1.37/ounce
11. Pure Vanilla Extract
Costco sells Pure Vanilla Extract for almost 75% cheaper compared to Walmart’s price.
Costco: Pure Vanilla Extract, 16-ounces, reg. price $11.99, or $0.75/ounce
Walmart: McCormick Pure Vanilla Extract, 2 ounces, reg. price $6.97, or $3.49/ounce
12. Bulk Spices
Spices are one of the best deals at Costco — I often buy ranch seasoning, steak seasoning, ground pepper, sea salt, and cinnamon at Costco for much cheaper than I can get at other stores.
I do frequently see low-value McCormick coupons (like for $0.50 off) that help bring Walmart’s prices down. But even still, the cost per ounce at Costco is much cheaper.
Costco: Kirkland Pure Sea Salt, 30 ounces, reg. price $3.39, or $0.11/ounce
Walmart: Morton Sea Salt, 4.4 ounces, reg. price $1.27, or $0.29/ounce
Costco: Hidden Valley Ranch Seasoning, reg. price $10.89, or $0.54/ounce
Walmart: Hidden Valley Ranch Seasoning, 1 ounce, reg. price $1.88, or $1.88/ounce
13. Nutella
Nutella is 27% cheaper at Costco compared to the next lowest retailer price we could find. And if your family eats Nutella like mine does … having a two-pack is worth it.
We do occasionally see Nutella coupons that can drop competitors’ prices even lower. But since we can’t use manufacturer coupons at Costco, sometimes we beat the Costco price by using our coupon at another retailer like Walmart.
Costco: Nutella Chocolate Hazelnut Spread, 2-Pack, 33.5 ounces each, reg. price $14.69, or $0.22/ounce
Walmart: Nutella Chocolate Hazelnut Spread, 26.5 ounces, reg. price $7.97, or $0.30/ounce
14. Almond Butter
You can save $0.12 per ounce when you buy almond butter at Costco instead of Walmart. I’m picky about almond butter, but since I’m also picky about getting a good deal, I’ve searched all over for a brand that’s both reasonably priced and tastes good.
Since almond butter coupons are rare, I usually end up paying the regular price. But Costco has the best taste and best price, hands down.
Costco: Kirkland Signature Mixed Nut Butter, 27 ounces, reg. price $7.99, or $0.30/ounce
Walmart: Sam’s Choice Almond Butter, 12 ounces, reg. price $4.98, or $0.42/ounce
15. Walnuts
Costco’s chopped walnuts are cheaper than Walmart’s chopped walnut options. Instead of dishing out more for the same thing, plan to save 60% when you buy your walnuts at Costco.
Costco: Kirkland Organic Raw Walnuts, 3 pounds, reg. price $7.99, or $0.16/ounce
Walmart: Great Value Chopped Walnuts, 8 ounces, reg. price $3.68, or $0.48/ounce
16. Excedrin
If you’re someone who gets headaches often, you won’t get one when you see the price of Excedrin at Costco. You’ll save $0.03 per caplet when you purchase Excedrin from Costco compared to Walmart.
Costco: Excedrin Extra Strength, 300 Caplets, reg. price $18.99, or $0.06 per caplet
Walmart: Excedrin Extra Strength, 200 Count, reg. price $19.73, or $0.10 per caplet
17. Half-Sheet Cake
Tell me where else you can get a half-sheet cake filled with delicious mousse for $24.99. Spoiler alert: You can’t!
Half-sheet cakes at Walmart start at $48.16, and IMHO don’t even come close to the delicious taste of Costco’s. The price per slice of a half-sheet cake from Walmart is nearly double the price of Costco's.
Costco: Half-sheet cake, serves 48, $24.99, cost per slice: $0.52
Walmart: Half-sheet cake, serves 48, $48.16, cost per slice: $1.00

18. Restaurant and Entertainment Gift Cards
I’m a huge advocate for buying discounted gift cards whenever possible. It’s probably the most overlooked money-saving strategy out there.
And Costco is one of my favorite places to snatch up future savings with discounted gift cards. Especially gift cards I can use for restaurants and gaming purchases. The savings get even sweeter during Costco holiday deals that come out around Black Friday and Cyber Money.
Expect to see $100 worth of gift cards for $79.99 (or cheaper) at Costco — that’s automatically a minimum of 20% savings.
Current Costco gift card deals:
Cold Stone, Four $15 E-Gift Cards ($60 value), $47.99 — 20% savings
Domino's, Four $25 E-Gift Cards ($100 value), $79.99 — 20% savings
Cinemark Theater, $50 E-Gift Card ($50 value), $39.99 — 20% savings
TopGolf, Two $50 E-Gift Cards ($100 value), $79.99 — 20% savings
19. Hot Dog Combo at Costco’s Food Court
The hot dog combo is for sure one of the best things to buy at Costco when we’re talking about bang for your buck.
Costco hasn’t raised the price of their all-beef hot dog and fountain drink combo in 30 years. And when you see how big the hot dog is, you’ll see how much value you’re getting!
Costco Hotdog and Soft Drink Combo: $1.50
