I patronize my LBS by paying a premium for parts and having them do all my service. In exchange, they'll go out on a limb and help me out when I'm really in a pinch. The good service more than pays off for the premium IME.
The pandemic has been a bit rough since QBP and other distributors have been having supply chain issues. It's a bit weird for me to get told to go on Amazon to buy chains, but hey I still ask them each time. Recently they had some M8000 brakes for my new MTB build which I was surprised about, given their difficulty online even. It took me about 2 milliseconds to decide to purchase them.
