I am biting my nails waiting for my volt to get here. It is Saturday and the postal tracker says it won't be here until Monday. I just realized my starter kit will only have 5 cartos. So I wii probably be needing to get som juice soon. I am looking for some advice about which suppliers are best on quality. I also am trying to figure out if I should use vg or ( oops I can't remember the other on). Or a 50/50. Since I will be using refillable cartos is there a problem or benefit using one over the other.
