I like both the LBSs that I frequent. One is very high end and I enjoy their group rides, but I never buy anything there because frankly they are wildly overpriced and don't have parts lying around for the bikes that I flip. The other shop I frequent I LOVE to buy from, but it's always random used parts or small things like crank bolts or rim strips. They always have this stuff in stock, and they are quick and easy for small cash purchases. EVERYTHING else I buy online, because it is often faster than ordering at a shop, I don't have to pay tax, the selection is MUCH better, the prices are always lower, and I often know more about EXACTLY what I want than the register-jockey at most shops.
