I was really disappointed when I went to Macy's last week. I went prom dress shopping with my sister and we found 2 dresses that she loved. We decided to buy both of them so that we could take them both home to get my parents' opinions. I went to return one of the dresses, with the original receipt, and they told me that I could only get partial store credit and partial cash. Apparently because my sister had used her Visa giftcard to pay for the dress, they wouldn't give me cash for that portion of the return and would only give me store credit. The only reason they are even getting 2 stars is because I was able to find a few decently priced things after I shopped just about every rack in the store. The return policy on the receipt says that a return for cash can be made if you have the original receipt. Apparently there is some "fine print" that they didn't bother actually printing.
