The only time I ever try to negotiate is the end of the season, like now, when I know that they always can get closeout from the factory for cheap, I know this becuase I've gotten bikes cheap now before. At any rate, they treat me well, when I was but a newb they showed me how to properly roll a tube onto the rim to avoid popping tires (right after I just popped a tire) and they showed me how to put the new tube on and gave it to me free of charge. They always do quick checkups on some noise or problem whenever I ask. I am pretty lucky.
