Good deal for anyone who has bought Guitar Hero or Rock band with Guitar or solus and wants the drumset! I've got the GHWT with Guitar from argos @ £48 (thanks HUKD) and now I can get the drums to go with it! - nearly whole set for under £100 :)
For info they definitely DO work with GHWT. (edit with one less drum - WT has 3 drums & 2 cymbals and rock band has 4 drums only see posts below)
Last time they had a deal with Rock band it didn't seem to be time-related but stock related - it just suddenly went up in price and then up again - so unsure how long it will last but I can't find these for any less than £50 anywhere else.
