GAS STATION
Nothing makes me happier than reading the CNN ticker on TV at work and seeing that I am paying less than the national average for gas, which was $3.52. I was squealing inside like a little girl when I remembered that last night I paid only $3.20-something per gallon. Teeheehee! My only minor gripe is the drivers who missed "Gas Station Etiquette 101" when they were 16 and think it is okay to pull up to the first pump they see rather than pulling up to the very end to make room for other people.
GROCERY STORE
Don't bother. Shopping here defeats the purpose of saving money at the gas station because everything is more expensive than Albertsons or Smith's.
