Go with the Hess stations,they're among the cheapest in the area.One thing to watch out for is the station on 535 right outside the Hotel Plaza blvd Disney entrance.I think it's either a Mobil or Exxon,I'm not quite sure but about 5 years ago if the gas in the Hess stations was 2.15 a gallon this station had their gas at like 3.05,then at some point like maybe 3 years ago they just stopped posting their prices,they may be at the pump but I've never bothered to check,right now with the Hess stations at 3.75 this station is probably charging $5/gal.On another thread about this topic awhile back someone said this station pays a lot more in taxes for some reason, I've also heard a law might make it illegal to not post the prices outside.
