Gasoline prices where to buy OnPost (AAFES) or Off Post?

If you have a smart phone, download the GasBuddy App. You can look up and compare gas prices anywhere. I purchase mine at Sam's Club, which is usually 10 cents per gallon or more cheaper than AAFES, and much closer to where I reside. Also, consider this. How far will you commute for alleged gas savings? Do you have to deviate from a normal route of travel for work or leisure activities? The average passenger vehicle has about a 15-gallon gas tank. A difference in price of 5 cents per gallon is only a 75 cents savings. How much fuel will you burn and time will you waste to purchase gas that is less expensive? That is something to consider. Gas is consumable and proven that it will be purchased, regardless of its price, even when it was or is $4 per gallon.

I buy fuel (diesel for me too) at Sam's Club. I pay an annual fee to be a member of Sam's Club, but it's worth it. We shop there for some things, which is a savings, and fuel is just about always cheaper there than anywhere else in the area, including on post.

So I'm saving money, but I'm not helping the Army much.

I like to buy on base, mainly because I would think that AAFES standards would be higher than the guy on the corner that sends money back home to his terrorist buddies. Also I have had some bad experiences with buying cheap gas at el cheapo (seriously a gas station name not trying to be racist) gas stations having water in their gas.
