Heh here's one for people. In my province at least the best way to get cheap 24/7 fuel in every corner even the podunkest no stoplights villages is to get a free membership with the local fuel co-op (UFA here)
I regularly save 2-10 cents a litre and have 24/7 access and even shitters and showers in most locations all for no extra money or work on my end other than the initial sign up.
