Starting 7/29, Circuit City will have a promotion for Xbox Live accessories:

Save $20 with the purchase of any 2 XBOX LIVE accessories $19.99 & Up

The ad has two 1600 points cards next to this offer.

Some buying methods:

(1) Buy it right now this week. Go back to CC on Sunday and match this offer. You may receive a 110% PM. YMMV on that.

(2) Buy it on Sunday when the store opens. In-store pickup isn't valid unless the store is open (due to the 24 minute/$24 guarantee policy).

(3) May not work but if CC is sold out, go to Best Buy and see if they will match this offer.

Cross your fingers that CC doesn't change this on Sunday.
