That is a solution right up my alley - free! We don't really deal with natural disasters here. Occasionally we have small floods or a big storm. I can recall two hurricanes in my lifetime (I'm 28-years-old), but most places have electricity etc. back the next day. We're lucky in that regard.
My biggest concern would be health problems or layoffs. We have the financial side covered and will be working on our food storage in the new year. Oh and preventing moths. Pantry moths are frequent in Denmark, especially if you buy organic items.
Yes, FREE is my kind of solution too!
I'm so glad you're working on food storage! It's like having your own in house insurance! ;)
