Come on, man. Reselling Humble Bundle codes? That's not only against their terms, it's also what you call a "dick move."

I don't want the Steam codes to go to waste. (I used Origin.) Its not like I am trying to get rich off it.

You are violating their terms of service and reducing demand for their product. Demand which directly benefits charity.

I am sorry you feel that way. I don't much care.
