Yes, Walmart has the most lax return policy ever, especially with food. Like no questions asked unless you’re obviously abusing the policy. If you buy any food item and it turns out not fresh enough for your standards, you can just take it to the return area and they’ll tell you to go get another while they do the work on your receipt.

This can be extrapolated further to get the “Walmart lifetime warranty” on anything they sell whether you bought it there or not.
