Amazon's Gold Box Deal of the Day is Mass Effect 3 for $29.99 (50%) for PlayStation 3, Xbox 360, and PC

.  While Bioware and EA have tried to bill the final installment in the trilogy as a place where newcomers can jump on, that's stretching it.  Technically, you could start playing at ME3 and the massive Codex would fill in the backstory, but that's not as much fun as playing the backstory.  The half-off is great because it gives newcomers the opportunity to save $30 bucks on picking up the whole trilogy, so today you could pay $66 on Amazon for all three Xbox 360 games (PlayStation 3 doesn't have the first Mass Effect).  Despite the highly controversial ending of Mass Effect 3, the Mass Effect series is a high-water mark in gaming, and not to be missed.
