Those are some great tips for places to buy your own dough. Following up on some of the suggestions to make-your-own:
1. If you make ahead and freeze, put the dough in a gallon freezer bag and squash it out into a flat rectangle-- that way it defrosts much faster than a ball of dough.
2. There have been a couple of recent bread fads (ie "artisan bread in 5 minutes with Zoe Francis) where you make a big batch of dough, then leave it in the fridge. I've read that these also make good pizza dough.
3. If you have a bread machine, this is a great use for it.
Good luck!
