I worked at best buy about 7 years ago right outa high school. this kinda of thing happened Daily, but we were told to give the customer the benefit of the doubt as all returns were to be inspected by us computer techs. IMO it looks like the person accepting returns at that store looked on the side of the box to verifiy its contents without getting someone who actually knew what they were lookin at, and put it back on the shelf.

Did you use a credit card?
