$15 is how much their supplier charges them. They pass that cost on to the purchaser, no more, no less. They make nothing on a different LED color.
That's how much they are grossing, not how much they're netting after the cost of goods and overhead. I have a friend with a bakery that brings in lots of money, but after she pays all of her overhead and employees she still struggles.
The fact that they're made in the USA was actually really important to me. I try to buy American when I can. It's not always possible, and I do my share of slow-boating, but I do like the fact that it's made here and it was a factor in the purchasing decision.
As to the person who said they're a status symbol - I only know two other people who are serious vapers and both recommended the Provari to me. I didn't want to spend that much money, but my boyfriend pointed out that knowing me I will go through a bunch of devices trying to find the best one, and wind up spending more than I would on the Provari. Then he wound up buying it for me. Two nights ago I bought him one. I have absolutely no regrets, I love it already; the hand-feel, the fact that it's fairly idiot proof (because I am often an idiot), the fact that it's so solid and feels indestructible. I got the polished, btw. We bought them from our local vape shop who will handle the entire warranty process if anything goes wrong, and will provide a loaner until ours come back. It had nothing to do with status (who's going to care?) and everything to do with quality and service.
Now I have one more used black one on the way from eBay as a backup. The more I use it, the more I like it, and
at this point I have no desire to buy anything else. Just like if I had to replace my car I'd buy another Subaru.
