Exactly how small is your small town? Sounds pretty tiny if the local grocery store only carries Wonder bread! :-) Hm...
http://www.peapod.com partners with Netgrocer.com and will ship non-perishables to your house...maybe bread would fall in this category??
You can buy Kashi cereal products online at
http://www.kashi.com. Their Kashi Good Friends cereal is only 1 pt per 3/4 cup!
If you have a big enough freezer (or even if you don't have a large freezer), you could make a special trip once a month to a larger town & stock up on those essential items that are low in points (frozen veggies, bread-which you *can* freeze well, meat, fish, etc). To help keep things "fresh" in the freezer, you could buy one of those vacuum sealers, which will keep frozen items good for longer period of time without freezer burn. I bought one awhile ago...it's called the "Food Saver" and I bet you could buy that online, too.
