Costco has a pretty interesting policy when it comes to returns, especially with food. If you buy something, like a bag of chips or a box of cookies, and it doesn't live up to its sell-by date, you can actually return it—even if it's partially eaten! Costco is all about keeping their customers happy, so they're pretty lenient with their refund policy. Just make sure the food isn't expired, and bring proof of purchase to make the process smooth.
However, it's a good idea to be mindful when buying in bulk. Costco's refund policy might be generous, but it's best to avoid purchasing large quantities of something you haven't tried before. This way, you won’t end up with a ton of something you don’t like and have to go through the hassle of returning it. Costco’s approach is really about balancing great customer service with practicality.
