I bought a bread machine off of Craigslist for $10.00, and it quickly paid for itself. Each weekend I make a loaf of bread for $0.78. Below is the basic recipe that I've been using.
*Note that homemade bread does not contain preservatives, so it does not stay fresh for long. Once my freshly baked loaf cools down, I slice it and then freeze the slices. I take a slice to work each day, and it thaws within a couple of hours.
