Righty ho then

I was having a think about my Karate "Running Costs" and I was horrified at the amount of Strappping Tape and Voltarol and Tiger Balm I get through and that's not even mentioning Ibuprofen etc.

So given that a small tube of Voltarol is nearly £5 in the Chemists I had a quick look online and couldn'ty find anywhere cheaper - in fact it was more expensive when you added the postage costs. Also couldn't seem to find bigger ttubes either....
...so anyone got any good sources to purchase these costly "Essentials" ? - if so please share.
