Two Sapphire Radeon HD 6990s are left. Waiting for other offers! Actually this is the best time to mine Bitcoins, because the price is growing!
Did a forum member buy one from you? Would be nice if he would show that you're a valid seller, because $300 for a 6990 seems too good to be true.
I can confirm he is a legitimate seller. I purchased 1 6990 and he sent me a copy of the parcel service receipt. He also sent me a website to track the progress of the package. I will update this thread when I get the video card.
