Guitar Hero 3 Legends of Rock game plus guitar controller are now included in the 30% discount section in Woolworths' closing down sale. Wii version is £51.99 reduced to £36.39 and the PS3 version £54.99 reduced to £38.49. Just bought one of each at Woolworths in Earlestown.
I'm aware this isn't as good as the £35 HMV price, but Woolworth have lots more stores and, as I haven't been able to find a £35 one in HMV. probably better availability so hopefully more people can grab one.
