In the next week to 10 days I will post how I keep and maintain an extensive pantry and freezer stockpile. I started stockpiling about 18 months ago and I won't go back to shopping for groceries the way I used to. I will post pictures and sample documents of how I keep track of everything. I also hope to discuss how stockpiling for some people can end up being hoarding.
It is easy to go to the "darkside" in stockpiling and become a hoarder. I learned quickly that I would never let stockpiling control me. Instead I find the principle of stocking up on sale items and buying in bulk a unique way to save money and stretch my grocery budget.
