I didn't exaxctly stockpile batteries, but I did make sure that I have a sufficient quantity that I can rotate them around and have them last a nice long time -- 8 of them; 4 25R's and 4 HE2's. And I got a new charger, just 'cuz the one I've been using is now about 2 yrs old, and when charging 2 batts at 1A, it tends to get extremely warm, so it may be near the limit of its useful life. Plus I was really pleasantly surprised at how inexpensive the Xtar chargers are -- they have such a great rep, I was afraid they must be real pricey, but they're not -- the VC2 Plus is great, since it shows you how long it will take to charge!
I sorta-kinda stockpiled PG and VG, mainly because I'm NOT psychic, and I would hate it if somehow the FDmotherfuckinA somehow made it difficult to buy those chemicals. Not an extreme stockpile -- got a bit over a gal of PG now, and about a qt and a half of VG, so that should last me for some time.
The only really massive stockpile I've acquired is the 3 liters of 100mg nicotine -- considering I vape between 3mg and 4mg, and only about 50-ish ml a week, that 3 liters should be a lifetime supply. It's in the freezer, in dark glass, inside cardboard boxes, so I've taken every measure for longterm storage that I reasonably can.
I've now got 300ml of my shisha strawberry, which will last a while, but I sure hope Inawera can weather the TPD storm in the EU.
