My annual cost of ingredients for liquid is less than $40. May be I need a fresh battery, every couple years may be I need another mod. It's so little money it might as well be free, like chess. But there are people who want to endlessly explore new flavors or they are newbies who need coaching. The vape shops are for them. They'll pay more in the shops, their choice. The treatment of the shops by the governors is sadistic. There's no other word for it. Hopefully the courts agree and eventually we can get those governors out of office.Chess costs?
