"Pay what you want" is a false statement. When I wanted to pay 1 cent they demanded a minimum of one dollar. I may be a cheap ass for wanting these things for a cent but that doesn't change the fact that "Pay what you want" is a total and utter lie.
Sure, not what you want, but worth noting. Particularly useful if you want something on offer, but don't like the company selling them and don't want to support them. For instance, I can imagine a lot of people stiff EA when EA has a bundle available, and go 100% charity. :)
