Hard sales are not the way to go in this day and age. Soft sales dominate the successful business/customer relationships. I would not recommend this to anyone who uploads to YouTube for fun. I never EVER click on a hard sale in my PMs or "Shared With You" and I flag comments that are spammy. Go trade stocks or something. That way even if your videos are never famous you don't care because you can be "not famous" from your Rolls Royce. I'm going to investigate this further because it would be nice to get some more sales, but I remain heavily skeptical. If I have not modified this comment after the posting date, it's because I've stuck with my initial verdict.
