Send him to CigTechs and let him learn to buy his own stuff, My husband recently startedvaping, and I don't mind answering questions and helping, but he has to do some suff for himself.
ETA: If you have not attended the Windy City Vapers meet (2nd Saturday of the month at Pop's Pizza, Roselle) there are always people there that can help with RBA's and will give him lots of good advice/help.
