DIY is way cheaper, than buying your e-liquid from vendors. At first, there's a minor investment in all the materials needed, in order to make your own liquids. However, the money spend on it, will outweigh the money saved, making your own liquids. For example, I have a liquid, that consists of 4 flavors, plus the usual VG, PG, and Nicotine base. When I make 120ml, it costs me $2.37 only. There's a sub forum here on VU (DIY E-LIQUIDS), with tons of information. Pay special attention to information provided by HeadInClouds (HIC). Take a look at http://vapingunderground.com/threads/guide-to-mixing-by-weight.22891/Welcome to VU! I'm always curious with how people start DIY. What made you decide this and what do you recommend to start?
