Google checkout charges .20, and for every $1 I spent on Adwords, I get $10 in transaction fees. So, check me here,
1) I get 100 transactions of a dollar each, which comes to $100.
2) Google takes 2% and $.20. Transaction fees would come to $22.
3) I spend $2.20 on Adwords, leaving my total transaction fees to be $2.20.

Do you think this $1 to $10 is just a promo thing, or will be forever?
