This research cost me a huge amount of time, and was quite expensive too. Dealing with mylar bags was very frustrating. This is an anxiety-free solution.

Maybe you're the one who recommended mylar bags to me. If so, I hope you spend the afterlife in a place where they only serve Liptons tea bags.

In addition the Pleasant Grove 5 gallon bags smallest quantity on amazon are 20 for $64.95. The big sistema containers are on sale right now for $9.95, normally they're around $17.

edit: downvote all you want, mylar mafia. You're the ones causing all the stress on this forum around storage solutions and you deserve to be called out.
