If this is the ONLY shop and you want the option of buying local, you could always contact a representative of the products you like that are in this one LBS. They'll talk to the guy and if they're concerned that he's not representing their brand properly, they'll educate him or pull products.

I know, it's convoluted and not really worth the time, but it's an option.

And yes, too many brands will not care, but there are plenty that are extremely concerned.
