Love Rock Band so much you find yourself pining for some rock-and-roll antics while on the tube to work? Well we have the cheapest deal around for Rock Band 3 on the DS. It's £10.09 at ShopTo, but I expect stock to dry up in the next few days so don't waste time fretting on your wallet. It's the full Rock Band experience with a great list of songs you can strum and drum along to with the stylus, only now you can wander around in public screaming profanities as you miss a vital chord. Terrific!
