I bought Street Fighter IV at buy.com and after checkout and everything, click on CLAIM your 10 dollar on next purchase. They give you the account for shopperdiscountandrewards.com.with your Coupon code. If you did not get it, the number you should call should be there to claim your code.
Once thats done. Call them to get the Coupon code for buy.com. Put that in when you buy Killzone 2 at buy.com.
Then cancel your membership for shopperdiscountandawards by calling them and click on some number. ( Dial 2 to cancel membership etc)
Both are still available for $53.99 (save $6) w/ free shipping!
