I'm a newcomer to Arizona and recently checked out Haus of Vapors in Phoenix. I was so impressed by the owner, Drew, that I had to come check out his Tempe location. They carry more juice than I know what to do with. They've got over 140 flavors, more hardware than other places, and incredibly low pricing. The place is on Mill Ave. across the street from Arizona State University with parking behind the shop. I highly recommend vapers to check out this spot.
