Pretty sure they have a copy or two at Rockover climbing. I'm also 99% sure they'll have copies at the shop in Awesome Walls Stockport.
I haven't been in years, but seem to remember a fairly decent shop in Manchester Climbing Centre, so that's another shout depending on whereabouts you can get to.
They may well have it in Ellis Brigham or Nevisport as mentioned above, but I haven't been in for a while.
