Quoted from jalpert:No way. If the deal is good, by the time you post the seller has 10+ calls. Good deals get pounced on immediately. However, if you post and then seller gets 100 calls in addition to the origial 10+ it could very well kill the deal.
It can't help, it can only hurt.

EDIT: I'm ASSuming this only pertain(t)s to Good deals. I posted a $2300 DH because that's not a good deal, and it has been posted for like 9 months. Of course the price did drop a little after I posted it...hmmm.
