Game are selling The complete Rock Band Instrument pack and Rock Band 1 Game for £79.99 only available in store for xbox, ps3 and the wii.
Seemingly offer is good at least until wed 5/08/09 as game update offers every wed according to one manager.
You may have to ask if the game is included, I only found out when a manager told me in a local store all other store's didn't offer the game as well until i asked then they checked.
I just picked up the last 360 version in Perth
My appologies if already posted
