O.K. here's my thoughts. I agree with SB for the most part, conditionally. If that is the type of relationship you want with that pro shop, and they are ok with it, then fine. You buy your stuff somewhere else, take it to them, and they charge you to put it on. BUT if they put it on, and say do not worry about the charge, then you are beholding to them. You do not have to honor that idea, but it does not change the fact that they treated you better than you treated them. And generally, if you do pay a little more once or twice on an accessory, the shop will usually put it on for little or no cost. Then as time goes on If you treat each other right, they will often lower their item cost to you, on some if not all things in their shop, and still hardly charge you to assemble or put it on, or rig it out. This is called building a relationship with your customers. It keeps them coming back. I mean really, do you think a guy who spends his money at " JOES BOWS " and has for the last 5 years pays list price for the items he buys? I know personally, I don't , and I don't spend near what many other people do in my area. But I have formed a relationship and the owner has earned my business, SO I give it to him.
