If selling is a Sport or Hobby or Profession that you enjoy, then the final price should have a lot of bearing, however if you're just a casual salesperson like me you should accept whatever price you are comfortable with. Is the extra $100 dollars worth the effort involved with continuing the "For Sale" process? Is money very tight right now? Will you miss the money next year at this time? These are all questions that I ask myself when an offer comes in on an object I have up for sale. I generally price an item in the high end of an acceptable range and consider any offer within that acceptable range using the above criteria.
Clear as mud?
