Ok, i'm in a situation. I bought the fifty-one trio from a kiosk at the mall. I'm just about out of cartridges, but this thing has assisted me on my first day without a smoke in about 11 years(and im 24). I know it's ridiculous to go out and buy carts continously for this thing, and i'm willing to spend more money on a new PV. What would you guys purchase next? PS - i need to order liquid ASAP. im gonna purchase enough carts to last me til i can get some liquid, and hopefully order more stuff by tomorrow evening. What do you guys recommend? Thanks!
