Accidentally tossed my receipt after grabbing a few things from Costco, not thinking I’d need it. Of course, one of the items turned out defective a week later. Rather than waste time guessing what their return policy allowed, I ended up reading through https://costco.pissedconsumer.com/review.html to get real-world takes on how they handle situations like this. Some returns sounded too easy, others a bit messy—but it helped knowing what to expect before heading back to the store.
