It wasn't too long ago that I was wondering why gas stations still had dual signs for cash and credit posted at the pump, since the prices were always the same. These days, I've been noticing the reason why: Stations are offering customers a big discount if they fill up with greenbacks.
These discounts aren't insignificant. You can find a price discrepancy of as much as $0.10 a gallon. To paraphrase Sen. Everett Dirksen, a dime here and a dime there -- and fill up enough times -- and soon you're talking real money.
Particularly when a gallon of gas was over $4.00, I wonder how many motorists realized they were paying a higher tab for using plastic. When it cost $75, $100, or more to fill your tank, did anyone really carry that much cash in their pockets?
As tempting as it might be to blame the gas station owner for what might seem like gouging, credit cards eat into the already slim profits that gas stations produce.
According to some estimates, credit cards are used in 80% of all fuel pump transactions. But several sources cite merchant agreements with credit card servicers Visa
ConocoPhillips led off the big profits parade last week when it reported that earnings had surged 41% over the year before, while Foolish wag David Lee Smith suggested BP
The federal Energy Information Administration says retailers and wholesalers account for about 8% of the total cost of gasoline, while refiners like Valero
If you still want to use plastic instead of carrying around the equivalent of a second mortgage in your pocket each time you want to fill up your gas tank, you might consider a gas card. Many offer rebates that exceed what you'd save by paying cash. Just make sure you pay the bill in full every month, or the interest will far outweigh the extra pennies it would have cost you at the pump.
Even though gas prices have come down significantly in recent months -- I saw a station selling regular gas for $1.99 a gallon the other day -- filling up the family car can still give you an ugly jolt. But paying cash can end up saving you a pretty penny.
