Usually 101vape, sometimes madvape, smartvape, vaporking, hoosierecig for hardware. For juice I've bought a lot of places but but a lot from Namberjuice and AVEjuice. Keep wanting to try Mtbakervapor but they don't give descriptions of the juices, have to read the reviews to try and figure out what the heck the flavor is supposed to be which is a total PITA in my book.
Just bought a Duke mod from Fogsauce and will buy a Reo from Reosmods in the next week or so as well.
