I just fill a blank cartomizer. I label them with Avery file labels. If I don't care for it, I'll give it a try again a little later since the taste can change over time. I'll also have them already filled so I can let people I want to bring to The Vape Side have a taste. I've got a few people wanting to convert that way.
A lot of people drip. I know next to nothing about dripping, though, so I can't really tell you much other than you'll need the proper gear for it.
