Places to look:
Ebay
UKCSportpursuitGo Outdoors (Good prices and 10% price match if you find it somewhere cheaper)
Cotswolds (Ask committee for 20% discount code)
TKMaxx (Just drop in regularly, they often have Craghoppers, Berghaus, and Mammut at a ridiculous price)
Don't be afraid to go secondhand and check around to see if you can borrow stuff.
-If anyone has a group shelter then those would be useful
-Also, if anyone has any kit they'd be happy to lend out please post it up (if you want to borrow stuff then ask here)
If you're not sure on what to get then feel free to ask!
Remember beg, borrow and steal!
