Not in the slightest but then I dont mind paying a premium for a quality juice from a vendor that Ive trusted for years. In all the time Ive ordered from them, every single bottle has been spot on and remarkably consistent.
Sometimes you really do get what you pay for. I didnt buy cheap cigarettes when I smoked.I dont buy cheap juices either.
That's the thing , I don't buy cheap either and the DIY step was carefully planned to actually allow me to vape better controlled mixes.
I get my concentrates from only two sources , Mt Baker which everybody HAS to agree is High Quality and Crystal Liquid which is a premium supplier also. The Nic juice I got was from , what I taught at the time, a good source turned out they had no clue what the nic base had in it.
