"OBO" means just that. Make an offer--A specific price with a clear statement of what it covers or does not cover (shipping, PayPal, etc.).
OBO is NOT a request for a buyer to respond with "what is your best price". The seller has already made an opening offer and it is incumbent upon a potential buyer to make a specific bid.
Classified buying and selling (especially OBO sales) is very similar to an auction, just not as formal and the price frequently goes in the opposite direction from an auction. In an OBO classified the seller asks for the best price they think they can get and then, if there are multiple potential buyers, they secretly bid against each other with specific offers.
Many Audiogon auctions don't start out at the sellers best price because there is a hidden reserve. If a buyer wants to buy they are forced to make a specific offer.
So buyers, if you are serious make an offer already otherwise don't waste the sellers time.
