I want to give you my input as a retail shop owner. Granted, I do not sell bows or
anything to do with hunting. but man, to buy that many bows from a dealer, I would expect him to treat you as a V. I . P.
These are not small purchases, and if you have been his loyal customer during all these purchases, you would not expect the guy to treat you as "just anyone".
I give my best customers extra special treatment to let them know just how very much I value them as my loyal customers and appreciate their business. I would be completely up front with the guy, quote him the other price, and let him make the call... does he value your business? or Will he risk losing you?
