I try to use my LBS (there are several, some better than others) for some items, just to help the locals. But frankly, you really need to provide something you can't get on Amazon or Ebay these days to stay in business. If they aren't providing excellent service, there is no point. You can get just about anything cheaper even with shipping delivered straight to your door these days. I am lucky to have two decent LBS within a mile or two of me. I wish them well and they seem to do good business. I am not really in their sales demographic but I do try to buy local even if it costs me a few extra $$. However, I have to admit, as time goes on I do this less and less. The last time I bought tubes, I ordered them.
