I started vaping to quit cigarettes. I am 63 years old and retired and live on a fixed income I would like to know where to go for starting formulations and supplies that are reasonably priced. I use nicotine 12 to 18mg in my juices I buy. I have found these two become very costly.I am an ex lab formulator in the Ink and Coatings industry and I'm familiar with formulation procedures and terminology. Please help with any information you can supply thank you and have a great day. Many Thanks. Rod
