This was not the case at Anthropologie yesterday.
I went in to exchange a lovely cardigan that Josh had so thoughtfully bought for me for Chanukah. In mustard yellow. The sweater had just been marked down to half-price that morning, so I was surprised to find the cashier only giving me the marked-down price as credit. I didn't say anything because the gift receipt didn't reveal how much Josh had actually paid (maybe he'd gotten it on deal?), but I did call Josh afterwards to ask him exactly how much he'd spent.
He'd paid retail, which meant I should have gotten an extra 80-odd dollars in credit. I called the store. They apologized and said that if I could track down the original receipt they'd credit the difference. Fortunately Josh had saved it and today they made good on their promise.
I bought this sweater with some of the credit. Gift receipt policies aside, I love me some Anthro.
