Here are a few frugal ideas:
I've slowed down to 60 mph while on the interstate. I read that is about the speed to get maximum miles per gallon.
I bought a coupon book a while back from http://www.entertainment.com/discount/home.shtml
Right now they have a special...if you reserve the 2009 book, they will send you the 2008 book free. It's full of buy-one-get-one free meals from restaurants all over the metro area...definitely worth the money. When we go out to eat, we buy one meal, get one free, ask for an extra plate and share our food with BK. We always get water instead of tea or cola...saves $3-$4 dollars.
I've started playing the CVS game. Tonight I went there and bought a small crockpot that was on sale for $12.99. I had $10 extra-care bucks that I had been given from a previous visit, so I only paid $2.99. Then when I got the receipt, there was another $9.50 extra bucks from what I've spent there the last few months. I get stuff there all the time free or almost free. It's so much fun to get the sale paper and see what kind of deals they have each week.
I bought a liter of Philosophy Amazing Grace shower gel/shampoo from QVC as a Christmas present for myself Dec. 2006. It came with a pump. A year and a half later, I still have at least 1/3 of the bottle left and I use it exclusively for my shampoo. Nothing special about this lasting so long...it's the pump that does it. Put your shampoo and shower gel in a pump container...it lets you control how much you use and it lasts a long time.
If you use liquid soap, buy a large refill (generic...like Fred's brand) and add a little water when you refill the pump. It keeps the soap from being so thick and makes it last longer.
We have breakfast for dinner once in a while. Eggs, toast, grits (or Cream of Wheat), pancakes. Even if I use a whole dozen eggs, they are only about $1.50 (which is less than a meat dinner).
More to come...
