Charlie,
I used to sell the second most expensive tools in the world. (Mac tools, Snap-on are the most expensive) When people would try to get me to lower the price, I would just say "NO"! Explaning that I was in business to make a living, not friends.
If you lower the price, people think that your product must not be worth what you are asking and deside that they can get the same thing cheaper elswhere. They need to see the value in a good wrench (or hand made item) and that in the long run it is worth spending the extra money for what you are selling.
If they press you on price a bit, just say "Money talks and BS walks, lets see what color your money is." If they don't buy the item right there and then forget about it. They won't be back, they just want to see how far they can push you.
I'm sorry to hear about your fustration but, I understand the problem and you must just keep knocking on doors and trying to get the sale.
Lets face it, if it was easy everyone would be doing it. It takes a special person to sell special items and you have the tallent to make the special items you just need to work on the sales end a little harder. It is there in you, you just havent found it yet. Keep trying, you can make it work.
