Hi eric, welcome. You'll get 1000 answers to your question...
Forum Suppliers <---this is a forum link for suppliers. Local vape shops tend to run higher in price (Kanawha county here)
I don't know anything about Halo e cigs, do have some of their
juice. From a beginner the seemingly most followed progression is to get a "mod" (variable volt and variable watt battery), and a decent
tank (Aspire
nautilus, Kanger etc..) You can use the above link to access the online retailers for both juices and equipment.
The search box at the top of every page is a good place to use. You can reply to any post to get the first 5 in, giving access to the other parts of the forum. Good luck.
