Hi! Welcome!
Are you thinking of doing vacuum sealing because you can get better deals on healthy food in bulk?
I haven't done the vacuum sealing. I find our best method of shopping healthy is meal planning around the sales.
I have considered vacuum sealing in one instance -- I can buy cheese in bulk from a local cheesemaker at a big discount. But it's big chunks, so I couldn't use it all once opened before going bad..... This is really the only instance that has tempted me.... Oh... And maybe meat -- vacuum sealing before freezing large quantities of meat might preserve it better.
