Case Lot Sales are wonderful but since I buy cases of case lot items I never know what is a good price the next time they come around.

Step 3: Three Month Food Supply | Food Storage Made Easy
Some friends buy things like Mac & Cheese and Ramen as a snack food for their teens figuring that it could be meals in a pinch if needed, also a can of Cream of ___ soup over rice or pasta makes a low cost emergency meal. I store some of these because my family has special dietary needs so we don't rotate as much as would be needed for a perfect 3 month supply rotation.

As others have said, if these foods are too expensive to do all at once, you can learn to make more very inexpensive meals from scratch and use the difference to buy more of the basics. Then eventually you have money to buy some of the already prepared items from what you have saved doing more of the cooking/baking yourself.
Also, the grain stores like Honeyville's (Utah, CA, AZ), Walton Feeds (Idaho), the "home storage" cannery or Discount Big Box Stores normal prices on grains, rice and beans can be cheaper than the "sale" prices at the grocery stores especially as some of the stores buy their grains and beans from these outlets and then mark them up by 50 - 100 percent.
