When a seller has a high price and the item fails to sell, its the same as if the seller has purchased the item. I always like to deal with ready, willing, and able sellers and avoid the "I would rather keep it than give it away" wannabees. However, I understand, if you feel its worth a certain amount, then ask that. When it doesn't sell and rather than lower the price, you raise it, you look foolish.
But then again, its a free country.
