Told seller I would be interested in a single unit shipped to Canada. Seller immediately asked for 70% upfront and 30% on delivery. I said I'm only interested if escrow is involved with either someone here on the forums or btcrow, seller declined escrow for the reason that he wants to order a 600gh/s card from BFL and does not want to wait for escrow. He then switched it to 50% upfront and 50% on arrival.
