The posters that suggested the bread machines are on to something...you can even find scads of them at garage sales, as they were a "fad" appliance a few years ago.
Also, Truble suggested getting yeast and flour at Sam's in the big pack (I think the yeast is in 1 lb bricks,) if you freeze in a tupperware container, it will keep for a long long time..I have used it 6 months later, (frozen) with success.I have also found the yeast in 1 lb packages for under $3 t restaurant supply stores (Last time I bought at Sams, I think it was two bricks you had to buy)...also you can split the opened bag of yeast with someone else who is baking their own bread.
you can also make your own pizza and stromboli dough, even dinner rolls and hamburger buns...just put the setting on "dough". I have been making mine by hand, but I used to make the bread dough in the machine, bring it out for a final rise (or prepare braids or whatever for a bread like challah) and bake in the oven. saves time for busy people, and you can sneak nutritious things into your "white " bread...top with an egg wash and some sesame seeds or poppy seeds
I plan to try my hand at sourdough, I am pulling out my crock to begin the starter today
