I usually use one shop for service, they know me, my riding style and the history on the bike. They are always nice and get great supervision from the owner, so I know I'll get what I need. I just want good quality service, when I need it at a fair price. I almost always have a few coupons for free coffee from a nearby coffee stand for the guy who did the work, it's not much, just a little thank you. I buy everything possible at the bike shops in town, but they can't stock everything, so I do shop around online and in Portland when I'm there.
