Amazon double fine sale

Here

What do you guys think about, I don't know much about the games so

Games, Stacking $7.50, Psychonauts $2, Costume Quest $3, oh so fine bundle which includes all of the games $10, all are steam redeemable, the bundle will give you separate codes for each game

Just put an US address and you can still buy them, do that for any other amazon download

EDIT: Thanks to movac who pointed this out | I should point out that the $2 Psychonauts deal is today only, tomorrow it goes up to $4. So if you're on the fence, decide soon.
