I admit I'm not the best at "searching" for previous threads. I'm looking for ideas on rotating "canned" goods, both glass canned and metal cans. I've looked around the net and found all sorts of things for sale and even just bought this; Neu Home 12 Refrigerator Can Dispenser - Walmart.com This one is "ok" but just by stacking the cans I can store almost 2x as much, but its hard to rotate stacked cans if you add to them every week and this one will not fit quart mason jars. I found one system made of plastic that you assemble and can be made to rotate tuna fish cans or the wide cans of fruit. My store bought stuff is stored on shelves like the chrome wire stuff you see in a commercial kitchen and the mason jars are on a deep industrial metal shelf system. How are you actually rotating your stored food? Do I need to just suck it up and rearrange my shelves after each grocery trip? Thanks.
