This response doesn't address the concern of the comment that initiated it. He was suggesting that your program which currently consists of 3 $50 chunks might be too expensive for someone to risk the purchase of the first tutorial.
If you could divide the beginning tutorial into a few smaller lessons, it would be far easier for someone to justify giving your program a chance. While $50 isn't a huge amount of money, your competitors have given consumers the ability to sample their videos for a much lower price.
If you can't divide the beginning tutorial, perhaps you could create another, shorter video from scratch, and market it at a cheaper price. Once you have established a reputation people may feel more comfortable buying the complete set of tutorials.
And the $50 starting price is why I'm not interested. I prefer the model of "micropayments" -- being able to purchase smaller increments for a lower cost. I need $50 too much to gamble it on a video. I can't be sure it'll be worth it.
