25% off any used XBox 360 games for the next few days. 3 game max. Here's the coupon:http://img301.imageshack.us/img301/632/ebc3006350uj8.jpg
Since used Blue Dragon recently dropped to $18, that means you can get Blue Dragon for a mere $13.50! I thought it was a fantastic game - the feel of Dragon Quest 8 with a job style similar to Final Fantasy 5 (but better) - although some disagree with me.
Aside from Blue Dragon, there's also Mass Effect for $30 (so $22.50 after the coupon) and Eternal Sonata for $35 ($26.25 after coupon).
