It was me that it happened to.
I had a gold leather Kristin hobo which started flaking after I'd used if for less than a week. I took it in, wanting to do an exchange, and got the runaround and was told that it had to be sent in for "repair". I left it at the store, came home, and got really frustrated, since I'd only purchased the bag less than a month prior. I went back the next day and told them I did not want to wait for a "repair" and would like to exchange. I got the black leather Kristin instead, and realized the next day that the tag was not attached. It was loose inside the inner zipper pocket, which made me think that it either was the floor model or a return. I did not call or go back to the store. Instead I wrote a letter to corporate regarding the entire incident.
