With my first new "real" bike, a Schwinn Le Tour, the LBS threw in some cheesy black rubber foam grips which were fashionable at the time. Nowadays I don't haggle. If I like the bike, I buy it, and that's it. Having worked for a bike shop when I was younger, and knowing the sleepless nights my boss and his wife endured due to being pretty much always a day late and a dollar short, I am less included to haggle with bike shop owners.
