I have been freezer cooking for several months now, and one easy way I save money is to rewash the large gallon size freezer bags I use. If I put 10 muffins in a freezer bag, once the muffins are gone, I wash it by hand and hang it up to dry. When I am doing my next freezer cooking day, I just scratch out the old contents’ label and write a new one. It may not be pretty, but that doesn’t matter. (Note—I never reuse the bags that have stored raw meat.)
There are many ways to save money, but I read somewhere that the best way to save money is on the little things. Saving $2000 off the sticker price of a car is great, but it is only a one time savings. If you break your gourmet coffee habit and don’t buy coffee out everyday for several years the savings is also significant. If you save money on many little things, well, the savings just multiple.
