Found this on another forum, thought it would be worth sharing here.
I personally would not buy something like this from Amazon UK, would defer to a dedicated reputable computer dealer, but some folk will choose Amazon because of not knowing better, seeing it cheaper or whatever, its a concern and from thread I found this on, not that uncommon from Amazon … its obvious what is happening, some folk are ordering an Nvidia RTX 2080 Ti, then when it arrives sending back a similar sized lesser card to Amazon for full refund saying it was a mistake, also as worrying is Amazon are putting these back in stock with an Amazon checked sticker and selling it as new again or even second hand with discount … their return staff who check obviously don’t know enough to tell the difference from a full RTX 2080 Ti to a much cheaper GTX 1080 Ti (or even lesser spec card) one of same size.
AFAIK, Amazon track mobile/cell phones by their IMEI number, they really should be tracking expensive graphic cards like this too by serial numbers or suchlike.
I don’t know how widespread this scam is? but this guy in video bought three RTX 2080 Ti’s from Amazon and all three were not 2080 TI’s … cause for concern I’d say.
