They sell on Ebay too. A good seller would mention

They sell on Ebay too. A good seller would mention the box damaged or opened in their listing but most don't. When I bought my cheapy the listing said brand new, but the whole top of the box was ripped open and heavily taped close. I feel we shouldn't worry too much about these sellers as they are limited. They are selling damaged goods in which otherwise would be in the trash. But for those selling unvalid codes, that's another story.
