Weekly Money Tip! Here is a great idea to save money on electricity but only if you are going to use it a lot. They say in the video that a toaster oven uses 50% less electricity than a regular oven. I bought an upgraded toaster oven last… year and I use all the time. I do all my baking in it and even warm up food in it. I only have to use my regular oven for large items now. It also doesn’t make my house so hot in the summer when I’m baking.
