Its been a while since I listed anything and was wondering what a "Best Offer" means. I mean I know what a best offer means but what (as a seller) do I need to know about it. What does it cost? Do I HAVE to take the best offer? If I list something for $100 and my best offer is $1 am I required to sell it to them for that amount? Thanks - I did a quick search on Ebay itself but boy is that NOT a user friendly site - at least to me.
