In reply to Richard Baynes: Go outdoors in Clydebank have a reasonable selection of climbing kit at a good price, although there was a big climbing sale at the weekend so they might be low on stock (there is also one in Coatbridge but I've never been so I don't know how good it is)
If you see a good deal in a shop then shop artound online for the best deal, then see if go outdoors sell it. If they do then use their price match to get a good deal.
