Where do you get the book?
Emergency Essentials has a sale on beef roast @29% off, and sausage crumbles @ 43% off when purchasing 12 cans.
I recommend accessing the preview and checking out the table of contents. You'll find that it is packed with far more information than virtually another other preparedness book.
Where some books might recommend raising rabbits for food, for example, this book provides complete details on the subject - from raising and taking care of rabbits to proper killing and butchering. (Same for chickens, goats, etc).
