I recieved a MK bag as a gift. It has the tags on it and everything, never used. I tried exchanging it in the store for something else and was told they absolutely don't do any exchanges without a reciept. I was so surprised, I didn't want money back I just wanted to change for a different style. I've never bought anything from MK before. Is this true for all stores, or have any of you had any luck exchanging without a reciept?
