Costco vs. Walmart: Which One Has the Best Deals on Snacks?

Snack foods can quickly drive up your grocery bill, especially if you've got kids. The best way to lower your bill is to comparison shop so you make sure you’re getting the best deal possible.

Many shoppers walk through Walmart's doors because it boasts "every day low prices." Shopping at Costco can be a great way to get the most bang for your buck, but only if buying in larger quantities makes sense for your household.

If you do a lot of your shopping at Walmart but also have a Costco membership, we looked into prices on five popular snacks to see which retailer makes the most sense financially.

More Shopping: The Best Costco Buys To Grab Now For Fall

  • Costco's cost per unit: 27 cents per ounce

  • Walmart's cost per unit: 29 cents per ounce

Costco sells large boxes of Oreo cookies for $12.99, which many think are only beneficial for larger families. However, the box contains individually wrapped sleeves. This helps cookies that aren’t being eaten right away avoid going stale too quickly. 

If you'd rather keep your grocery bill down today and don’t mind spending a little more per cookie, Walmart's Oreo cookies may be the better option at $5.24. 

  • Costco's cost per unit: 61 cents per bag

  • Walmart's cost per unit: 80 cents per bag

A popular snack in my house is popcorn. The kids eat it after school and it always shows up at movie night. While many popcorn brands are available, we love SkinnyPop. Both Costco and Walmart sell a box of 28 individual bags for $16.99 and $22.49, respectively, which are great for snacks. The biggest difference between Costco's SkinnyPop popcorn and Walmart's SkinnyPop popcorn is the cost. Buying at Costco means you’ll save more than $5 on the box, which is a considerable savings.

  • Costco's cost per unit: 36 cents per bag

  • Walmart's cost per unit: 44 cents per bag

Both Costco and Walmart sell big boxes of Goldfish crackers. However, unless your family eats a lot, they can go stale pretty quickly. Luckily, both retailers also offer large boxes of individual bags of Goldfish crackers, which can be ideal for school and after-school snacks. The biggest difference between the two is price and one is a clear winner.

Costco sells 45 on-the-go packs of Goldfish crackers for $15.99 or 36 cents per bag. Walmart sells a 30-pack box of Goldfish crackers for $13.12 or 44 cents per bag, making Costco the better option. 

  • Costco's cost per unit: 87 cents per pack

  • Walmart's cost per unit: $1.39 per pack

If you’re looking to add a healthy snack to your pantry, you’ll want to try Wonderful pistachios. Both Costco and Walmart sell boxes with individual bags of different varieties, including sea salt and vinegar, roasted and salted, and chili roasted. 

Costco is going to significantly reduce the cost at $20.99, but this is the only size package of Wonderful pistachios that they sell. Walmart might be the better choice if you want a smaller amount as they have many different package sizes, which provides more flexibility. But for this comparison, the 24-count pack of Wonderful pistachios at Walmart is $33.25.

  • Costco's cost per unit: 50 cents per bar

  • Walmart's cost per unit: 66 cents per bar

Nature’s Bakery fig bars are a great snack for both kids and adults. Each package contains two bars and is non-GMO verified. Purchasing Nature’s Bakery fig bars from Costco can be a great option for some families because they offer a variety, with boxes containing both blueberry and raspberry flavors. However, you need to commit to a large box with 40 bars for $19.99.

Purchasing Nature’s Bakery fig bars from Walmart requires you to pick a single flavor for $11.82, but the box is smaller. However, like many other items, Costco significantly reduces the overall cost.
