I don't really like that it shows the total cost of the materials.
What's wrong with showing the price? They sell the materials not completed pens so naturally they are telling their customers (you) what the prices are. Your customers are not going to the Woodcraft site to find out what the materials cost and even if they did, so what? Your customers are paying for your craftsmanship.
As far as showing me, I agree. As far as showing prospects, I don't agree. Ok, I understand where you are coming from, but I wouldn't tell prospective customers to go to the site to design a pen, and see that the cocobolo burl pen I'm selling for $110 shows $12.19. Granted it's not cocobolo burl on the site, but they don't know that. I like the idea, but not attached to a pen parts retailing site with prices showing. Just my 2¢.
