That's weird, then maybe they will let you exchange. I was just going by what their policy states. I'll tell you right now though, if I made that my policy at a store and my employees weren't going by it. I'd fire every single one of them on the spot.
it states the store policy on the bottom of the receipt, "exchange must be made with in 7 days" so, that is what it is. I have made exchange in store few times, and they all cool with it, just keep ur receipt and tags on, item must be unworn condition.
