If you can afford to, do both (but pick a different "free" game from GS). Even though the GS deal is good, I'd have a hard time paying more for a used game than for the same game new. $80 for 3 games works out to $26.67 per game, whereas the BB deal is $25 after coupon (remember, even if your BB doesn't have the good ggc, they probably have the $29.99 and up system-specific ones).
