Depends on the price difference. If it costs you £1 in fuel to do the round trip across town to put 50l in to save 50p then only a fool would do it. I'm not sure it would work anyway, but I can see some fuel chains trying it out. Worst case is queues of cars at garages waiting for the price to drop, causing congestion.
