I have a breadmaker and i use to make my own bread all the time.
But i really do not find it cheaper than in the store...but then again it is only $2-3 for a load not $4
Plus i find that we actually eat more bread because it is so fresh and yummy and squishy and smells so darn good
And i think you end up cutting the slices thicker too.
But hey...give it a try...especially since bread is so expensive near you
