I'm with Tony on this one. Charging to shoot a bow would me a huge mistake in my opinion as well. At the shop I go to, anyone can shoot anything they want, just have to ask. They have many different bows of the same model, so they usually have one that is real close to fitting the prospective buyer. Also, about your comment about bringing the bow back after it was bought on E-bay. This is where shops can make money. I know at the shop I go to, if you buy the bow there, they will set it up for free with whatever you want on it. If you bring in a bow bought elsewhere and a handful of parts, you will pay for the labor.
