How are you?
I'm fine, thanks for asking.
Are you interested in this system?
Yes, I am. Are there any problems with it?
Everything is great, except I have lost the remote.  I am willing to come down in price a little bit.  Make me an offer.
Well, I guess I could find a replacement remote. I'd be willing to pay $235.
I can't go that low, but if you meet me in the middle at $260 we have a deal
I'd be willing to go as high as $250, and I'll come by to pick it up so you don't have to mail it.
Ok, I guess I can do that
Okay, great, I'll be at your house tonight.
