Reason 4, Price Changes Prices change a real lot. I don't have the time to baby sit this site every single time a price change happens or a delivery slowdown forces prices up. And when a price changes the customer tends to hold me responsible. It creates hard feelings and tension when I have to raise a price. I sell a lot of high end beautifully figured Guitars like McNaught, Jacobs , JET , PRS, Pearlcaster , Quicksilver and many more.
Prices have to quoted based on the actual guitar.
In fact I lost many sales that way when all my PRS prices were posted. The smart customer checks things like Condition, Features, Options, Beauty, Playability and Sound Quality. Customers like these are not very intelligent buyers. But sadly the not very intelligent buyers outnumber the smart buyers 90 to 10. You don't want to be the Idiot who gets his prices beat by every local dealer.
