I agree that the pricing formula is problematic and doesn't apply across the board. I sell digital image downloads and people commonly think that these should sell for $1.00 each as if I haven't spent hours finding, improving, editing, photographing, advertising, and uploading the images. I only charge slightly more but I can tell I get less sales because of it. I offer bundle deals at a great discount, but still it's all very difficult. Some people value some work less than other. Maybe this isn't helpful, but go with your gut as to what you feel. Formulas aren't always in tune.
