I have been looking all over trying to find US suppliers with close to china prices I found a place to buy my joye 510 (cignot $35) and I found they have awesome prices on e liquid too. but 5 carts for 5 bucks china I can get 10 for 2.38. I know Im not going to get china prices in the US but their has to be better then $1 a cart, so I come here and ask all of you were do you buy your carts what do you pay so I can find the best place. also drip tips I am thinking about getting one but honestly im not sure exactly what they are or why they help. I thought at first they were just to keep liquid from going in your mouth but I like the fact that they wont melt so they seem more durable. So please someone tell me whats the deal with drip tips and should I or shouldn't I get one.
