As I am not so patiently waiting for my starter kit to arrive, I am doing some research on refilling etc. I purchased several packs of prefilled carts with my kit, but am fairly certain I will be refilling them myself after I get comfortable with vaping. I want to be prepared with some juice before this is a necessity. So, my question is, how many refills from a 5ml bottle, and a 30ml bottle? Just want to make sure I have enough juice on hand initially so that I don't get stuck without and have to turn back to the analogs while I wait for a shipment. Waiting till I try the 4 different flavors I got my carts in before I decide on a juice flavor, but need to know just how much I should buy to start. thanks!!
