I prefer Mason style jars for tobacco storage but they are out of stock everywhere but online. Online 12 jars cost about 9 bucks but shipping is 23 bucks. Will zip locks work? I really don't trust their seals much. My wife has Food Saver but they might off gas. I've read about Mylar bags, but I just want to buy some time until jars are available. Any thoughts? Thanks in advance.
