There's only 18 cards left according to the website. Sale is a week from now, so they are possibly all gone by then?
While it is possible, I highly doubt someone wouldn't wait for a week to save $100 off Newegg or $170 off Tigerdirect prices. There have been 4 "purchases" in the past couple hours with none of them fulfilling the payments to the addresses. Once they pass their allotted time frame for payment the cards will appear back in stock.
