@aliazharsalim I know a lot of people already having trouble affording groceries, who could greatly benefit from buying bulk supplies and canning them themselves. Just because a country is developed, doesn't mean that food supply chains are guaranteed... ask some of the poor who had to wait days...
Brilliant idea. I live in a small house and food storage (even for everyday needs) is a pain. This is a great idea that I may have to try. Thanks!
