What are these variables besides cost, supply, demand and their availability to obtain wholesale. The way I see it (and I am an MBA not that it matters) is that this would be a super sought after product that would have people lining up to buy it because they couldn't get a penelope either because of cost or availability. The only people who wouldn't buy this would be hardcore GG people and they aren't a factor anyway in this case (not the demo you are going after). I think as was proven by the terminator, this product would be viable at a minimum retail price of $60. Being that the penelope is widely regarded as a better product he would probably have room to charge $15-30 more.
So the only real question is can he make a profit at that number. Will people pay that price to be able to experience a penelope that is in no way a cheap knockoff? I think yes.
Furthermore he will again be the first to the US market should he carry it soon which was huge advantage with the terminator when it first came out. From looking at their website when it first became available, they could hardly keep stock on the shelves.
I think they should absolutely carry this because there's profit to be made and it will help them to maintain their reputation for getting new products that no one else has and not just another discount vape retailer
