Buy cheap, stack deep I love that!
Sounds like you got a great process going. The old refrigerator I assume its not turned on since your canned foods are shelf stable? I never thought of using an old fridge for storage but thats a great idea. Nice shelves, and they dont get Dusty!
The fridge hasnt worked in years. But it has nice shelves which are now filled with home canned soups, stews, stocks, jams, and jellies. The freezer section is where we store dried pasta and noodles in bulk.
Everything stays nice and clean.
Im pretty sure we could go 6 weeks with just the contents of the fridge alone.
Good luck.
