Creating A Supply of Food Storage with $5 per Week
This article has a list per week of what and how much to buy of a certain food using $5 per week for a full year. Keep in mind that that's for two people, so you would have to adjust how much per week depending on the size of your family, for example if you are a family of 4 you should plan on $10 per week. That would be a total of $40 a month to build up a pretty basic year supply of food. So check it out and see if it might be something that works for you.
