Both show out of stock, as I said. You won't be buying any cards through them. Newegg, Amazon, Outlet PC, Superbiiz, B&H Photo, these are the places you are MOST likely to even find a card in stock, and the prices are astronomical when you do find one.
My advice would be wait until Volta, which should be coming out in the next few months or so. That might alleviate some of the lack of supply for graphics cards across the board, because Nvidia has no plans to ramp up production in order to increase availability of current Pascal based cards.
Any way you look at it though the situation is a huge pile of dung. Putting in notifications for when stock is available at the major sites seems to really be the only way to even GET your hands on...
