I think you are making too many assumptions here. First, you are saying that people are willing to pay $60 for a CD. Especially when they ask "How many pics on that CD are of me?" and the answer is "I have no idea". Many people may say screw it, I its not worth my $60. Second, you are assuming that he needs double the customers to equal the revenue he would get from $60 a CD. So basic case would be that 10 people choose the CD option, which would be $600. So then you are saying 20 people will need to choose the $30 for 5 images to equal his $600. Some people may chooses only 1 pic, some 4, 5, 10, who knows... Too many assumptions. If the $60 per CD business model works for him, great. But if he doesn't try a different pricing structure, like the one to VW151, then he may be missing on some potential customers and $$$
