I went to Smyths in Cardiff to buy Rock Band Band in a Box for £39.99 after seeing the deal on here and was told that there was a promotion on to get the original Rock Band game for a tenner with the instrument pack.
Everyone knows that Smyths are doing the pack for £39.99 and the game has been as low as this in some places, but not a bad price for a bundle in store with lots of availability. There were six instrument packs on the shop floor and a stack of games behind the counter.
Also picked up Beatles Rock Band at £24.99 at the same time. Not the best price, but the local Sainsbury's had sold out at £21.99 and I wanted it there and then.
