Hmm-

Who wants to go out on a limb and order 20 thousand (or was it 200 thousand?) bags to split up for a group buy??? Yeah, right!

If you want to look for an alternative, try repurposing cereal/cracker box liners or mylar snack bags. Either type can be sealed with a clothing iron. I wash chip/snack bags, dry, reseal the bottoms, add single precooked and dehydrated meals, and iron shut. Use a soda straw to suck out as much air as possible and keep bag pinched as you iron the last bit. I can't speak to the cereal bags, but I've added boiling water to the mylar ones many times. Also, I have found that I can set these bags back into a pot of simmering water for additional cooking if needed. It is more work to repurpose bags, but they are at least something one can locate cheaply. I've used strips of larger bags to make "pillow packs" of resupply items from peanut butter to hand sanitizer. Seals on these do deteriorate over time, so don't make them up too far in advance.
