I also took the short walk to full-out crazy and ordered a small arsenal of the sale Provari 2.5 blemishes and floor models from Vixen Vapors. I have no plan to use any of them myself but was tempted beyond my ability to resist by the price. I couldn't use one even if I wanted to unless I bought the required batteries or the extension caps.
I should have bought the Provari 2.5 Mini PVs, but didn't. The Mini models are all out of stock now. The minis use 18350 button tops and I do have 4 of those batteries, but I don't have any 18490 or 18500 batteries for the "regular" Provari 2.5 models, and I purchased friggin' 8 of them.
Eight! You bought 8 of them and don't plan to use them?
Janet and I each picked up just 1 mini apiece and were happy 'bout that. But then we each have a number of Provari's so were just grabbing another for the $25 price. My dark side thought about getting a couple-more and flipping 'em ... but my better side won out so others might get a deal too.
