Unfortunately, I can't confirm the price for you because he didn't mention the price in the post he made. And he only sends the DM with the video to subscribers(and maybe lapsed subscribers). I should warn you that one of the reasons OF creators send videos through DMs instead of just posting them on their page is so they can hide the price from people who haven't subscribed. That way, if you subscribe specifically to buy a video, then see it's being sold for an unreasonable price, you might succumb to the sunk cost fallacy and buy it anyway. And if you don't, they've already got some money out of you. I won't tell what you should do with your own money, but I would suggest you wait for a subscriber to confirm the price, because there is a non-zero chance he is selling it for something ridiculous like 50 or 100 dollars.
