I bought a surround recevier about a month ago from bestbuy, an upgrade from my last stereo reciever. I recently decided to downgrade to a stereo setup for convience reasons. I normally save the boxes for all of my equipment, but for some reason I threw the box to my new receiver out. Have any of you had experience returning items without boxes to best buy? I wouldn't mind if i only got store credit.. better than a receiver sitting around here.
