I'm currently dealing with the same thing.
Here's what I'm doing for all my converts. Riva 510 kit, 5 pk boge standard cartos, 2 lr cartos, 1 drip tip and I order juices to match their personalities. I charge the sale prices that I can find and pay for shipping since I'm ordering from 3 or 4 places. I stockpile my crap, while doing noob orders. No more free kits, no more depleting my supplies. Hookers, gotta hand over some cash.
This last order, that I'm still waiting on, came out to under 70 bucks, which is what I paid for my ego kit. So, the converts have it a lot easier than we did. We walked uphill in snow and stuff.
Here's one thing, that I'm just going to throw out there: It's their choice if they quit the stinkies. You could have done the best job evar getting the right stuff for the right person but if some of those people are stubborn, unless you're gonna hand hold and fill carts 24/7, just know that you've done your part and walk away. My current convert is not going to use this thing, her girlfriend is making her try it. I'm ordering this for the girlfriend (who makes enough money to throw away this ecig money) more than my friend.
