A long time ago, one of the owners of my LBS told me he doesn't care if someone brings in parts they bought elsewhere. I have seen them assemble bikes direct bikes for people. They do good work and charge accordingly. I know they were pretty unhappy when Trek started selling online. That program kinda stinks for the shop, they ended up with bikes they didn't want because it turned out the person ordered the wrong bike. They dumped trek, and now the closest trek dealer is a lawnmower shop.
