I need to cut back on gas

I can't believe how much money I've spent on gas lately. Most of the trips are just to the grocery store. But several times I've gone to the store, come home and gone right back to the store because I forgot something. Each and every time it was something small or something that could have waited until the next trip. I'm wasting time and gas.

The worse part is that I'm wasting money and that definitely has to stop.
