Interestingly enough, I have seen gas stations very close to each other with very different prices. This was close to an airport so I assume the idea is to rip off tourists who don't have time to search for cheapest fuel before returning the rented cars. At least that was the only explanation I could find that didn't involve conspiracy theories (Catania, Sicily, Italy).
