I'm amazed AMD would pull something like this
It's probably not AMD themselves doing it, but some smaller shop in the UK with AMD in stock, and no greater connection. This kind of stuff happens all the time on Amazon since it's really hard to see who you are actually buying from.
Same with "only 2 in stock" etc, while they have warehouses full of that item.
The reviews for items are also all over the place since one of the companies working with Amazon might sell the item OK but another is paddling crap and Amazon piles the reviews together.
