IMO, dont expect the owner to go out of his way for you irrespective of whether you spent money there or not. You may have saved a few bucks, but the service you have probably lost isnt worth it. Doesnt really matter whether the owner is a dealer of a specific brand, if you have a warranty issue he is quite entitled to send you back to the place you bought it. (Unless being a dealer has certain conditions attached which I very much doubt??) I believe thats part of the sale agreement, that the owner will take care of any warranty issues pertaining to bows that HE himself has sold. On the other hand, some will help you with a smile on their face.
My advice, for what its worth, go and discuss it with the dealer and explain your situation, at least you will know where you stand with him or her.
And I use the word "you" rather liberally, no offence if it wasnt.

Good luck
