I believe the SCOTUS decision handed down today will have a large impact on the vape industry. I would guess that the majority of vendors we use are online only. Which means that they will now have to deal with the logistics and confusions of collecting a sales tax for their customer's home state. There does exist software to help with this, but that is an added expense too. I'm not sure what the final effect of this will be, but I'm afraid it's not going to be very positive...
