As mentioned in the Weekly Sales Preview for Dec 28th, Best Buy is having a sale on XSN games and all are $39.99. Combine that with the Best Buy printable coupons previously posted here on DealRush and the games then become $29.99 each.

If you want to try and make an even greater deal out of it, you can try and get them to honor the current XSN "Buy 2 games, get 1 free" sale currently going on thru Saturday. If they accept the coupons and honor the deal then you can pick up 3 games for only $60. This will vary on a store to store basis since some wont accept the coupon and honor the "free" game sale, but we've heard reports from a few lucky enough to receive both discounts so it's worth a shot.
