Mike, I use a vacuum sealer and a jar lid adapter to suck all the air out and let it go at that. Sugar stores well. I use the jars to store pasta and freeze dried soup mixes that I make up from bulk ingredients.
Sorry, was out shopping to accommodate the grandkids coming when things go south. Did you buy one? If so, what brand? What they nail you on is the FoodSaver bags. Last year, they went way up. I swallowed hard and bought some backup. Maybe, if I look at todays prices, I will feel better.
