From Cambridge University Caving Club - CUCC wiki
Contacted around 30 companies. So far we are getting pesto from Sacla, notebooks from WeatherWriter and a selection of tasty things from Tunnocks.
We should be getting some kind of discount at least on CurTec drums and Warmbac tackle bags; AlpKit are also to get back to us ASAP.
No from Makita; no reply from Hilti.
Please let me know if you have a company you'd like me to try asking.
