OK, Sammy you may well be right, but ARCO charges I think $0.50 to use a debit card, and they don't take credit cards and I get miles on my United Visa for using it. Gotta think about the overall cost.

If we buy 20 gallons of gas/week between us, we'd save about $7/week at a 35 cent price differential. Call it $4/gallon for rounding, and its $320/month or about $3,800/year or 3,800 frequent flier miles. At $0.35/gallon savings, that is $336 per year in savings. $0.10 per Frequent flier mile is pretty cheap. Plus you got to figure in the $0.50 per debit card charge 2x per week (two cars), that is another $50 or so per year of cost.
