I spent a couple of years building up my stash by spending literally every dollar of my discretionary budget on tobacco. I mean every dollar--I went months at a time without buying any books, music, new clothes, etc. I did this because I fear that a mail-order tobacco ban is a matter of when, not if, and I don't have a decent B&M nearby (not to mention the fact that Florida has one of the highest pipe tobacco tax rates in the country).
The ol' spreadsheet tells me I have 125 tins of Escudo in the closet. It is the blend above all others that I would not want to live without in case of the Tobaccopocalypse. I also have large quantities of my GH favorites, F&T Cut Blended Plug, and PS Luxury Navy Flake. Doomsday prepping, pipe-smoker style.
Needless to say, I'm not buying in quantity anymore. 8)
