There are disadvantages to living so far away from the big population centres! Yes jet fuel is cheaper than glow fuel but consumption is so much higher, but the fun level is also much higher. I buy my fuel at Gloucestershire airport for around 60p/litre which is a lot less than paraffin at the diy store, I also buy the turbine oil from the jet maintenance business at the airport for a lot less than model shops usually charge. Try Exeter airport, there is no good reason why they wouldn't sell you jet fuel, the problem is getting airside to the bowsers, not a problem for me because I fly full size from Gloucestershire anyway but several model jet fliers seem to have no problem getting permission through the Glos airport terminal to go airside to buy fuel.
