...can be interesting!
I've been waffling about stopping to fill the gas tank on my car for the past week. Not critical--still have about 1/2 tank.
However, gas prices have increased about 20 cents per gallon during that same week.
Finally broke down and stopped at a station that's about 15 cents per gallon cheaper than most of the others. Just as the pump started, someone began changing the price on the sign--increasing it 6 cents per gallon!
For once--and only once--my timing was good!
Not that 6 cents per gallon would break me--my car only took about 7 gallons.
