I'm happy to patronize my LBS any time I need anything and would miss them if they went away. They've always been fair with me and I trust them for advice when I'm not sure what I want to do. Bought 3 bikes from them, uncountable numbers of tools, parts, numerous maintenance visits, etc. If they can save me a few $ on something they're happy to offer advice on that too. Do I know everything about bikes? No, for sure...but they've never made me feel like a Noob and I've learned a bunch from them.

Could I get some of the stuff I bought there online for cheaper? Sure. Do I sometimes buy it online? Sure. But if I need advice who am I going to talk to at any particular online store?
