When it comes to buying staples in bulk, it’s hard to beat Costco for its sweet deals — assuming one has the space to store the mega-sized haul. That said, the temptation to shop with a well-priced competitor like Walmart — whose slogan, “Save Money, Live Better” plays out with dependable discounts — can be strong for shoppers who want the freedom to buy bulk and fresh items like meat, cheese and vegetables in one shop.
So, just how big is the price difference between big retailers like Costco and Walmart? This breakdown of what $100 of Costco groceries will cost Walmart shoppers can offer some clues. Interestingly, according to GOBankingRates’ data, Walmart has the cheapest grocery prices compared to other major retailers.
Here are some pantry staples along with some breakfast, lunch and dinner items from your grocery list to put some price points into perspective.
Quaker Oats Old Fashioned Oatmeal
- Costco’s price: $11.99
- Walmart’s price: $21.99
At Costco, a 10-pound bag of Quaker Oats Old Fashioned Oatmeal is a bargain compared to the same batch at Walmart, which costs nearly twice as much. When it comes to bulk pantry items like this, it could be worth it to save restocking breakfast for one big monthly Costco run.
Kirkland Signature Organic Applesauce
- Costco’s price: $12.99
- Walmart’s price: $21.50
These applesauce pouches that come in a 24-pack are a parent favorite, as they are a healthy, easily transportable, on-the-go snack. Given that kids suck these down at supersonic speed, stocking up at Costco makes sense, as they are nearly half the price as those sold at Walmart.
Kirkland Signature, Organic Extra Virgin Olive Oil
- Costco’s price: $20.99
- Walmart’s price: $38.50
Healthy and versatile, olive oil is a must-have staple for every home chef. At almost $19 cheaper at Costco than at Walmart, it’s another pantry item best bought in large amounts from the bulk retailer.
Kraft Macaroni & Cheese Dinner Cup
- Costco’s price: $12.49
- Walmart’s price: $16.89
Shoppers looking for some quick meal options will find better prices for Kraft Macaroni & Cheese Dinner Cups at Costco, where a package of 12 comes in $7.50 cheaper than at Walmart.
Kirkland Signature Thai Hom Mali Jasmine Rice
- Costco’s price: $23.99
- Walmart’s price: $41.99
The price difference for a 25-pound bag of jasmine rice — a versatile ingredient that can fill out many meals — is particularly stark, coming in at about $18 less at Costco than at Walmart.
Peet’s Coffee Major Dickason’s Blend Coffee
- Costco’s price: $19.99
- Walmart’s price: $33.99
Costco wins again in the price game for a two-pound bag of Peet’s coffee beans, selling the batch for $14 less than Walmart.
Final Take To GO: Grocery Bill Total
- Costco’s total: $102.44
- Walmart’s total: $174.86
The bottom line is that though both lists come in over $100, with the Walmart bill coming in at about 75% higher, it makes economic sense to stick to Costco for any bulk pantry needs.
