I actually only go to one shop now. for this exact reason. I got my mvp3, subtank mini, and a 15ml bottle of cosmic fog for 120 out the door. I have ended up developing a great friendship with the owner. theres nothing better then being able to hangout at the shop for a few hours and just vape and talk new devices coming out, cars, crazy things we did when we were younger and that we both think one day someone will turn a car battery into a vape and roll it in on a little red wagon. His mark ups arent high in my opinion. 12.00 for a 15ml of any brand. The shop is also extremely involved in the local community. We wanted a skate park, So a fundraiser started and warehouses are being looked at right now for a spot. but ive been to a different shop that wanted 5.00 for a taste and 22.00 for 15mls Needless to say, there will be bad people in the business but there will also be great people. My advice is to find a local shop thats got great prices and great staff and just go there.
