They now have policies to at first tell you their records only go back so far and than offer you a refund the lowest discounted price they sold it for. They say this When they have easy access to all of your transactions no matter how far back. The cashiers also make you feel like a jackass and say things like “it looks like you got your money’s worth”. This is my experience recently. It really REALLY changed my opinion about Costco and there return policy. The policy is “no, sorry no record of this” followed by “well maybe my supervisor can approve this but not for what you paid for it” then when you raise hell, suddenly they find your transaction and say “of course we would never not let you return it”. This is procedure for profit and it is NOT what the return policy states.
