In reply to abcdef:
There are numerous stores which offer discount for memberships of organisations such as the BMC and BCU. Plus any voluntary organisations, cadets, scouting etc.
For the sake of a BMC membership, i think mine was £15 you get 15% off full price items at Cotswolds. Loads of other stores offer the discount and Cotswolds are ones that stock the boot you want in your size, plus the BMC is doing quite a bit at the moment for climbers and walkers (subject to a huge debate!)
Food for thought!
