I found this site some time back. They carry dried food stuff and appliances.

Because we live rural, we are probably good for 60 days on food. I have been adding to the food stock, food with very long shelf life to add to that time limit.
One aspect of being able to stock food, is that we can take advantages of sales and over the long run we cut our food cost down by at least 30%.
Other aspect I have been looking at is setting up the homestead to be more self sufficient.
