I don't know if i'm allowed to promote something like this... but for you PC gamers humble bundle is offering a pay what you want for a large package of THQ games including Saints Row the The Third.
The current average payment is about 6 dollars the suggested amount is 25 dollars, well below the retail for the game alone. It's a good program that splits the money (at a percentage you choose) between the developer of the game, charity and to the humble bundle team.
