Not many brick and mortar 510 dealers...I can only suggest stocking up from cignot.com. Get you a truck setup..3 batts, attomisers and cartos, charger etc.....Juice is a tossup. If its affordable, Id hit up 3 to 4 vendors, at least 2 flavors each in 15 ml. What you dont like, you can throw in the classifieds. I can recommend highly admired vendors for all to help slow the searching to a screeching halt. The truck stops only carry super mini stuff, and that just wont do. So, lesson learned on stock here..so get it bought, get it here, and next round out will be easier on you and the pocket book.
This was supposed to be reply to little nitro up there.
Ok, after seeing the madhatter site, I say go to cignot.com, and stock up on 510 or ego items...3 batteries, 5 atties, 2 chargers, adaptor for truck if needed, 10 carts, 10 cartos (syringe if needed), and 60 ml of liquids stock(cignot or others). Might be sticky on cost, but you'll thank me later, and you wont be caught in the same spot for quite a while.
