Any Owner Operators use Shell Fuel Credit Cards in Small Gas Stations?

I have my own Rig and my Lease Company gave us Fuel Cards from Port Consolidated in Tampa Florida. I pull Port Containers and i was thinking of getting a Shell Fuel Credit Card. My Boss said that every friday Port Consolodated sends him a e-mail of the current Price. This Week is $3.88 a Gallon and in the Convinient stores like Circle K they are at $3.74. I easily can save $100.00 a month and $1000.00 a year in Fuel. Any Owner Operators know of any good deals of Fuel Cards out there since i no longer fuel in Love's or the pilots? Shell Credit Card is promoting a 5 cent discount of 50 gallons a month or more. Sounds Familiar?

 

Yea losttrucker, i am thinking of a Walmart Caard myself. If i can used the Shell and the walmart, i should be all right. The real problem that i forgot to add on my new thread is that i cannot track that fuel money like i want. Sometimes Port Consolodated price spikes and i dont want to pay over 4 bucks when i can pay for 3.74 a gallon. I buy my Shell Rotella and all my chassis greas and windsheild fluid in walmart. Thanks for the heads up.
