Since the Podium and Taylor parted ways before the merger, this is not a complete surprise (unlike the dealer status being withdrawn from My Favorite Guitars).
I don't quite understand what 'Preferred Online Dealer' status means.
http://www.taylorguitars.com/dealers/onlineIt used to be that a shop could not advertise that they were a Taylor dealer, no mention could be made in a phone book ad or on their website, much less put product up with a 'Shopping Cart' format. One had to look at Taylor's website and call the store to see if the guitar they were looking for was in stock. In order to be a dealer, the store had to be 'brick-and-mortar' and maintain their inventory.
It looks like Taylor's marketing structure has been aligning more with other large manufacturers, whereas before they did not sponsor artists or give away products in contests. It would be expected that there would be some changes, as the current VP of Sales came from another large guitar company. Let's just hope that the quality control does not go down a similar route as well.
As for the discount percentage, there are other companies that have successfully set the price levels, but savvy customers will always be able to find where they feel they are getting the most per dollar spent. If the idea is bring the actual sales price up, it's a little late for that because the 'standard' seems to have been set and dealers have set up their pricing structure to where they feel they need to be in order to be competitive. Playing games with MAP is always an option, as there are other guitar manufacturers whose MAP prices are the same percentage off as the 'deep discount' ones. Lets hope that it's not another instance of the 'tail wagging the dog' because when that happened with a string manufacturer, the tail 'won'.
I doubt that any kind of 'petition' would produce any results, as if the company feels that they no longer want a dealer to represent their product that is their prerogative.
Still, 'It's just business.' seems a little harsh because I'm sure there are a good number of people that have supported stores like these for very good reasons and it seems like the rug is being pulled out from under them.
