If you're looking for amazon payments, have you considered actually selling it on amazon? It costs nothing to get started selling, and you can usually get more than CL or Ebay for stuff that's sold out. I sold one of those asus 5970's for $800 a little over a month ago.
Yea thanks I put it up on Amazon. So if anyone wants one look there..$779....but if you're a Bitcoin forum member I'm still letting it go for the low low price of $650.
