I'll go to the bike shop to get a fork cut or a wheel trued, or if I know they have something I want and I'm willing to pay an extra 20% not to order it online. Near my university there is a "Schwinn Shop" that seems like it's been around for 40 years. It's the ****. Two great guys (father and son) run it and they carry Schwinn, GT, and some other new bikes as well as used **** EVERYWHERE.
I hate walking into a bike shop where everything is new and their cheapest stem is $35, cheapest pedals are $20. Sometimes I just want to dig through a bin of old, dusty parts to find what I need, for cheap.
