I've purchased from Sara a couple times before, and she's always really sweet, but the one gallon bags they sell are very small and VERY thin, and I had several puncture and decompress after a while.shopsimplerliving.com
This website is nice if you want smaller (1 gal.) bags and O2 absorbers in smaller quantities for getting started. I've put away a fair bit of food with 25 1 gal. bags and 50 300cc O2 absorbers.
