Ship me or deliver to me a brand new, unopened, boxed
HD 6990, and i will pay you 210 BTC. That's $756-840 according to the current MtGox rate of $3.60-4.00. Compare this to resellers selling this card for $709.99 with no taxes if purchasing out of state.
Send me your Bitcoin address beforehand. I will pay you after taking delivery. We may use an escrow service if you want, although I hope I am perceived as a trusted community member by now.
