This won't necessarily have the desired effect, afterall if we boycotted Shell, BP etc and maybe moved our purchases to the supermarket forecourts.....who do you think they buy their fuel from? The best way to make the oil companies notice is to REDUCE our consumption of fuel. Simply just shifting your purchases to other outlets does nothing. Besides, the margin on selling fuel at the forecourts is so small I doubt the likes of Shell or BP would reduce their prices in light of a boycott, they'd probably just shut the fuel stations, they make far more money elsewhere. If anything boycott the supermarkets, they have a lot more power with the Government.
