I have a vanilla visa that doesn't allow purchases outside of the USA and i want these two games. Ill trade steam games for them worth up to $20.

Maybe you have a specific reason to want to do it this way, but in case you just aren't aware of alternatives:
For example the prepaid credit cards from wirecard is what I used to use, back when having a credit card was really unusual in Germany :) (http://www.mywirecard.com/)
