It’s no wonder that these Volcano Digital Desktop Dry Herb Vaporizers are flying off the shelves! EXTREMELY Popular vaporizer! $599.00 + Free Shipping at Direct Vapor – but supplies are running out (UPDATE: 2/26/18: Only 5 remaining). I’m not putting an expiration date on this, because I’m hopeful that they’ll be restocking. Give it a try! Hopefully they have more in stock at this price!
