I have 1 $100 gift card. I have a Bitcoin wallet and would let it go for anything reasonable. 1BTC is a deal for me.
Contact me by PM if you want to work anything else out. Only limiatation is that you do not have to SPEND this $100 credit before July 30. You only need to create an AdWords account and enter this coupon information by that date, which would be July 1st, 2011.
