Fuel stops

Today with the price of gas and diesel going out of sight we need to know where the best prices seem to be.
Betty and I traveled Interstate 20 from Texas and the fuel prices ranged from $3.25 to $3.37 per gallon. The prices vary several cents per gallon if you pay cash or use a credit card or debit card. Credit and Debit cards are mostly the same price. If you pay with cash you save 3-5 cents per gallon.
I have found that Shell stations seem to be the cheapest per gallon. Kangaroo stations were the next lowest we found. Easy in and out is also a consideration that we all have to face. The stations that I use are easy in and out.
I do not care for Pilot, Loves, Flying J, because they are 16-17 cents higher with no discount.
If you are traveling interstate 20 then you need to fuel up at Clinton, Miss. at the shell station just off the interstate There price was $3.09 there and has been lower for six months.
In Meridian, Miss. a Kangaroo station had fuel for $3.11 and it was very easy to get in and out.
Breman, Ga. had fuel at a Kangaroo station for 3.11 also.
One thing I should note here is that I never buy fuel unless I can see the sign from the road. I drive a motor home and tow a car and the whole thing is 56 feet long and I am not that good of a driver in tight places.
When Betty and I travel we take note on how far it is across a state and we know the mileage we get from the motor home. Our fuel gauge never dips below the half full mark. the highest price we paid was $3.25 per gallon at a pilot. If you have some cheap fuel places share them if you would.
