Using this method accurately identifies the consumption rate of each product, whether it be shampoo, bar soap, laundry soap, catsup, cooking oil or whatever. Doing it this way you can plan your preps without having a glut of one product over another. Your preps will be very much more organized than before.
I hope this benefits you in your efforts to be prepared for life's unexpected challenges. Even though they may be unexpected, we know they're coming our way. It's just a matter of time.
Have a great prepping day!
