I've had a similar experience with some monitor backlights. I was sent a "new" product that, when I opened it, I found it had been cut up (which breaks it), adhesive backing removed, parts removed from packaging, etc. Clearly used, returned, and sold back to me unchecked as new.

Almost as frustrating would be the third party sellers who intentionally send me something other than what I order, claim a mistake and that stock is out on the original order, and then try to convince me to keep it with a discount (price less than what I paid but equal to what I ended up getting), like some sort of shipping shell game. This has happened to me multiple times, from clothing to computer parts.
