$20 EA coupon code, what should I buy?

Hey guys, I had troubles registering my first Dead Space code, so I was supplied with a new one which couldn't be authorized. (I am somehow authorized with the other key though hahah) They game me a 3rd one and a 20 dollar voucher for anything in the store for my troubles of me having to wait almost 7 hours to get help to fix everything.

I was thinking about using it on orig. Crysis and then having to pay only 4.95 for the game. Or I could use it on MoH and only have to pay 20 dollars for it. IDK, what do you guys this? I'd prefer to get a PC download.

Oh, I could also get Dragon Age: Origins for free with that code, or pay 4.95 for DA:O CE.
