I almost never buy clothes unless they're on sale. I can stretch my clothing budget pretty far sometimes by doing this.
I use a combination shampoo and body wash to make both showering and grocery shopping easier and faster.
I do my college homework while I'm at my job during slow times, that way I have more free time at home.
I try to consolidate all of my errands into one trip to town so that I don't use as much gas.
I use multiprotocol IM clients that support social networks and email so that I can check all of my accounts at the same time. More done, less time spent.
I try to buy shelf stable food and other groceries in bulk so that I can save money and not have to make as many trips to the grocery store, which also saves me time.
I ditched my cable bill in favor a higher speed internet connection and a Netflix membership so that my family and I could get more entertainment for less money.
I make homemade Christmas cards for my family every holiday season. It allows me to give them all better presents.
I like to eat at home as often as possible so that I can get more out of my food budget.
