I just wanted to mention that I had gone to other vapor stores in Madison and they were not as professional as I would have wanted. When I went to Puff Vapor last Saturday, the nice young man named Joe behind the counter helped me understand the things I purchased at the last vapor store. He went out of his way to really cater to my vaping needs. I just went back to Puff Vapor yesterday and I was greeted once again with Joe's expertise and professionalism. Puff Vapor is clean and I didn't feel uncomfortable what so ever! Anyone looking for a nice professional environment for your vaping needs should definitely go to Puff Vapor!
