What else do I need to buy while I'm there?
Well you only won the deck... although it does come with a spares pack and a drip tip lol
Pretty much what Brew said... if you buy the clone version, almost all the thingymabobs work... I would not buy the glass tank for the MTL... or bograt...unless you vape tank cracking juice
get a 3.5 or 5ml tank section
The airflow doodads, even though the clone ones work just fine in the authentic decks too. All the other things you can buy from FT and the like.
