I had it happen to me at MicroCenter. Got a mechanical keyboard, in a seemingly-new box. No return sticker on it. Opened it up, and the damned thing was missing like six keys and absolutely covered in gamer chud. Someone very obviously bought it, put their old keyboard in the box, and “returned” it. And whoever took the return didn’t bother checking, or mark it as an open box.
