I don't use Foreflight for fuel prices.. I do not believe they are quite up-to-date. I don't mind going over airnav.com nor 100LL to find fuel prices.
Having said that, if you wanna spend a little more, Garmin Pilot uses airnav.com's data to show fuel prices.. so I'd tend to trust that better. It is slightly more than Foreflight ($99 vs $75)... At least there's choice and competition
