This deal does seem different than the deals that I've done in the past where you order it on backorder and actually get it. Apparently, after reading more information on fwallet's site, this is a heavily backordered or even discontinued item.
When I did order a backordered item from buy.com in the past at the lower price, I got the lower price even though when they got it back in stock, they raised the price. I've ordered stuff before at Office Depot on backorder at the discounted price and they "adjusted" my price to the normal price after they got the item back in stock. I think it was RAM that I ordered at something like $30 a stick and then when my order went through, they charged me $69 a stick. I just returned the RAM.
