There exist cheaper buckets, where you get a whole month of 2,000 calories a day, not a mere 12 days; The price of that bucket is TWICE that of competition;

84.99 https://www.costco.com/330-Total-Serving...t.11649759.html

year supply works out to $63+tax for a month http://beprepared.com/year-supply-of-basics.html

look at the ingredients, count the calories, then compare the price; you don't need a vacuum sealer or dehydrator or or any special equipment to store whiterice/oatmeal/macaroni for a year
add some cans of refried beans, salsa, chili, meat ... which also don't require any special storage packaging
just keep it in your pantry, inspect pantry regularly for insect infestation, and eat some regularly its cheaper than this bucket

If you want to go longer term, buy some screw-on-buckets, or save some 2-liter soda-bottles, and do some dry-ice fumigation -- store whiterice/beans/wheat ... store away from light+heat and you're good for 30 years, DIY, without special equipment, without special order just by shopping at any grocery store

Also, a lot of research isn't required, food preservation is of interest to everybody, there are lots of resources to be leveraged:)
Wendy DeWitt seems do a good job of communicating some of these preservation techniques but she doesn't provide references; I like references, they promote beliveability so if you want some more references see
