Title text: And if you drive a typical car more than a mile out of your way for each penny you save on the per-gallon price, it doesn't matter how worthless your time is to you--the gas to get you there and back costs more than you save.
This comic is a jab at price-gouging shoppers who spend large amounts of time checking multiple shopping outlets for the best deals. The minimum wage is the lowest possible wage that a person could legally be paid, usually only targeted at providing unskilled laborers with an equitable level of income. Using simple math, the caption states that a person is effectively working at the minimum wage when they spend their time looking to save a few cents on their purchases.
The title text then goes on to talk about how the extra fuel consumption involved in finding cheaper gas leads to more extra money being spent on gas than is actually saved at the cheaper outlet.

- Ponytail: Why are you going here? Gas is ten cents a gallon cheaper at the station five minutes that way.
- Cueball: Because a penny saved is a penny earned.
- Caption: If you spend nine minutes of your time to save a dollar, you're working for less than minimum wage.
