I thought it would be kind of nice if there was some sort of counteroffer feature. You know; you have an article available for use for $10, with best offer checked, and someone offers you $1. It would be nice to be able to come back with a counter offer of, say, $7, rather than just rejecting an offer out of hand.
how about if a customer offers you a $1 it would pop up a message saying.... "Your kidding right"
Its a good idea but I'm not a big fan of the whole back and forth bartering. Really if you reject it and they really want the article they will try again with another offer or pay full price.
