Tried this before and only ended up getting guitar hero 3 but worth a shot again as that was a while ago.
I currently have:
guitar hero 3
guitar hero world tour
looking for any of the lips, guitar hero's, rock bands, dj hero (dont actualy have the decks so would need that too), and dance mat games (including dance mats)
cant seem to find much online but if you know of any deals around please shout up :)
can either paypal gift or bank transfer
