Bed, Bath, and Beyond carries all the various Debbie Meyer bags (green, bread, cheese, and cold cuts) online, and in some stores.
Similar options you can also get (all avail. on amazon's site) are:
- E.G.G. Ethylene Gas Guardian
- ExtraLife Fruit and Veggie Keeper
- Evert-Fresh Bags (like Debbie Meyer bags)
I was thinking of checking out the EGG or the ExtraLife since it just sits in the veggie/fruit drawer and doesn't involve washing/reusing bags.
