In my country these computer forums have rules that you cant ask for more than you paid. At least for the just released cards.
What country would that be?
I ordered an RTX 3060 Ti yesterday, only to have the shop call me and say it was a mistake and they don't actually have it.
Last week I saw a bunch of RTX 3060 Ti, at least 6 of them, with my own eyes in a shop but they refused to sell any since "they need them to assemble gaming configurations".
Most used card ads that are over a day or two old have already been sold and/or the prices no longer apply, but the sellers didn't bother to delete the ad.
So there's a long way between seeing a card listed online and actually getting it in your hands for the quoted price. The price for a used RX 5700 (XT) is €400 only if you manage to actually get the card in your hands for €400. Otherwise it's just random numbers on the internet.
