For many years I have enjoyed Oil Lamps on my Canal Boats , both the Heavy Brass Gimbal Wall Mounted Type as well as a couple of Traditional Table Lamps scattered throughout the Boat , I think them almost Therapeutic especially in the Winter in the middle of nowhere with some Coffee on the Stove . I have been using Bartoline Lamp Oil in 1 litre Bottles which I was originally sourcing from Uxbridge Chandlery at £2.20 a Bottle , I would often stock up when passing or even jump in the car for an occasional weekend visit should my supply run low . The problem I have recently faced is one of supply with none being available on my last two visits , this has caused me to shop around and I have been stunned with the prices being asked for this stuff , anything from £2.20 at Uxbridge to £9.00 at a Hardware shop in Tring , all for the identical Product by the same Manufacturer , in fact it seems that sellers are now speculating in this Product as if it were some Precious Metal , the pricing can be Breathtaking . In the end I sourced some from an Internet Supplier and because I bought in bulk it worked out cheaper than even Uxbridge when you factored in my Travel Costs. Does anyone have similar experience or thoughts to offer .
