Why do petrol prices vary so much between filling stations? On the same road I’ve seen a 5p-a-litre difference on what must be an identical product, while the same chains charge differently from town to town.
Weird, isn’t it? Of all the things we buy, the price of petrol is probably the most transparently disclosed before we enter the retailer’s premises, and yet this only serves to leave us wondering why how much we pay can come down to where we live, or even on which side of the road we are driving.
