It may be more common now, but I've had this problem with them before in the past. In one notable case I bought a new game console from Amazon.com and received a box that was so obviously used (seals broken, shrinkwrap missing, etc) that I didn't even bother opening it, I just returned it. Despite the price of the item they raised no objections, so they're probably used to this happening and just assume that most customers won't notice.
