Bought one liter of 12% for diy and now I'm ending up usually just blending it down with some 3.99 humco vg from Walmart. I'm actually enjoying the semi sweet taste... Reminds me of a mal light. I'm prob just weird but thought I'd throw it out there.
Lol.. call me strange, but I use that a lot too.
I know it's cheaper elsewhere, but it's a bit more convenient. I also have used CVS's brand.. which is USP 99.5%.. to be honest, it comes in the same bottle with different branding, I suspect it's just a rebranded version. Publix has it as well, and last I bought it, it was $3.19.
Also, I found that when you order a 255Ml bottle from Mt. Baker Vapor, it comes with one of those sscrew to close nozzles like what you'd see on a mustard bottle.... they fit the Humco bottles to a T. I'm saving those bottles for when I decide to go full out DIY... wash, dry, let it get totally air dry, then box it up with the nozzle open just in case.
