Thanks.
In response to B. The reason it is an MSRP (Manufacturer's Suggested Retail Price) is that it is against federal Fair Trade laws for a manufacturer to force retailers to sell for a required minimum price.
Actually it is the old fair trade laws that were made illegal back in the the 1970's. It has been legal for manufacturers to impose minimum advertised price policies since the early 1990's because of a US supreme court case. It is very common practice. I am bound by some MAP policies myself. If I don't follow them, the manufacturers will stop shipping me. No different than if I stopped paying them for the product.
I'm pretty sure that the case that made it legal to deny warranty for gray market products was the Nikon case. Nikon USA goes further than other manufacturers. Not only will they deny warranty service in the U.S. for gray market products, they will deny paid service as well and won't sell parts to third parties. So gray market products have to go overseas for service. All of that is now legal.

Seems to me that making a dealer "authorized" only if they sell for a specific price is actaully illegal. I'm not saying that Yamaha is actually saying this to dealers...but the fact that all authorized dealers prices on this are within ~$10 of each other is what made me think of this.
All said and done, I doubt that Yamaha is technically doing anything illegal, and I'll probably buy from Crutchfield, but it just annoys me that I have to pay $100 more for a warranty.
I can assure you, Yamaha is most likely very specific with their minimum advertised price program. I'm sure it is printed and explained in writing to the dealers.
The purpose of these programs is to protect the dealers against themselves. I have a gray market Yamaha digital piano. The price at the authorized dealer was $3800 and the price from the gray market dealer was $2800. The product I received is exactly like the one the dealer would have provided except that it was crated and I had to set it up myself and, of course, it has no Yamaha warranty. My assumption is that the $1000 I saved will more than handle any repairs over the next 4 years. I don't expect the unit to need any repairs at all. It is well made and known to be extremely reliable.
So you make your decisions and you live with the consequences. I'm not against dealers earning a margin. I'm a dealer myself. But there needs to be a reasonable price difference between gray market and white market. $1000 is just too much to overlook.
