Best Buy has a President's Day 12% Off printable coupon. Note, there are restrictions to this coupon so please read the fine print which there is a lot of on the coupon. Also because it is a printable coupon I would ask the sales person if it is good first just to be sure as some brick and mortar stores can be fussy about coupons. Expires on the 19th of February and is good in-stores only.
Also there is another printable coupon that is good for 10% Off regular priced Music, Movies, Video Games, and PC games. If you don't have Best Buy in your area I believe many big box electronic stores do coupon matching.
