Had GH WT on PS3 but selling that as bought Beatles Rock Band on XBOX 360 so now looking to back fill my collection with XBOX 360 Rock Band & GH games.
Been looking knowing this recently and its been over 29.99 just about everywhere till I saw this so thought i'd post it.
Seen various deals on here around the £20 mark but all appeared to be limited to single in store offers.
Hope this helps someone if not then never mind eh!
EDIT - link changed from Game to HMV as found it £2 cheaper! £17.99 is the lowest yet.
