I've seen a very small handful of these CPUs supposedly sold by Amazon.
The main problem with Amazon is that they sell returns without checking them properly. I've bought quite a few items from their warehouse (I don't any more it's only a quid or two cheaper now, shame) and so this could be a simple case of some dishonest erm, person, putting their old CPU in the box and sending it back for a refund knowing Amazon don't have the personnel in place to check it over properly.
I remember reading the reviews of an electric plane I bought. People were complaining that the toe plate was plastic and had warped out of line (meaning your planing was screwed). I bought one and guess what? it was full of wood chippings and the toe plate was about as square as my arse.
So back it went...
