I know there have been slightly cheaper deals but not too bad for the EVGA (one of the better brands) version of this card.
Also, I'm not sure if I see any stock here but could be worth a shot:
MSI RTX 3080 Ventus - $1,799
Edit: I know everyones skeptical about this. I don't see anything online about them other than that one reddit thread saying it's dodgy. But they are listed on staticice which is how I saw this deal. I've emailed them to confirm if they have in stock, but buy at own risk, use PayPal or CC for chargeback in case it falls through.
