Of course it does.
Let's use your TV analogy. I may want a 52 inch plasma but am not willing to pay more than $x,xxx for it. That means I have to buy a lesser brand name or wait for a sale or both. Plasmas were selling in the tens of thousands of dollars at one point; now they're much more afforable.
I want another BP and I have an idea of the qualities I want to see in it. I also have a price point that I'm willing to go up to. For me, not being a breeder or even an avid collector, I can wait years for everything to align and get the snake I want. Some people can't wait, for whatever reason, or don't want to, so they'll have to pay what the market will bear now. There are many more willing to wait or that have to wait because of finances than impulse buyers with money to burn, especially in this economy.
My point is that, depending on who you are and what you have to offer, you may not get the price you think you should just because a few people got together and made up a "Suggested Retail Price" list.
As the seller you have the option to wait years to get your full price. Or you can take a few dollars less and move on. It's all up to you.
