Welcome! I always get a kick out of people here saying that want to work in a vape store. I often times visit a local B&M and "hang out" with the owner (he and I have become friends and share common interests). Almost every other customer remarks that they should hire them due to their experience and love of vaping!!
After spending time with the owner and seeing the business up close, I realize that it is not something that will make you a ton of money! Between rent, utilities, insurance, up-keep, etc, etc. etc. there is not a huge profit margin. Especially when we can purchase stuff on line form places like FastTech for much less money.
