Charlies, I think he is talking about installing the peep sight or rest not throwing it in with the bow.
It costs them money why should they give it away?
I've been dealing with the same pro-shop for 0ver 30 years. If I buy something there they usually install it for free. They also have an indoor range and issue a range card good for about 12 hours with the purchase of a new bow. They treat me well and in turn I will pay a little extra there for an item than at a chain store. I also refer customers to them because of the good service and their knowledge. Just a good way of doing busuness.
