After some more thought on the topic:
Why can't a bonafide, established store make an order and get the business?
There could be any number of reasons.
Perhaps there's another Taylor dealer in town, or in a nearby town. Nothing would upset an existing dealer more than finding out Taylor sold a guitar to another dealer just because the dealer had a customer who wanted to buy one.
Maybe they could even have a Taylor or two on the floor for the high end person coming in as I'm sure they can't carry tens of thousands of dollars in inventory.
I think a more pertinent question would be "Why should Taylor allow a store to sell their guitars?"
Taylor is a premier brand. Why should they bother selling only two or three guitars to a store that just wants to be able to advertise that they carry Taylor, when there doesn't seem to be any lack of stores who want to step up and stock a fair representation of the Taylor line?
Not every store is the right "fit" for every brand. If Taylor has stocking minimums, and the store you frequent can't adhere to those, then maybe the store you frequent isn't the right fit.
I do apologize for my lack of knowledge in this area but I was just wondering why it's so exclusive.
Because there's a very real value in being able to say you're a Taylor dealer while, conversely, there's no real value in Taylor allowing someone to carry "a Taylor or two".
