Seller: Hello! Looks like you're in the market for an amplifier!
Buyer: Hi, can you tell me how long youu have had the amplifier?
Seller: I've had it a year or so. We got another one and although we could still use this, we don't need two.
Buyer: That makes sense. What kind of accessories come with it?
Seller: You'll be set -- it comes with an analog to HDMI conversion. You'll be able to connect to just about any network.
Buyer: Great. What brand is it?
Seller: It's a Marantz. Very reliable brand. I'm asking $949 which is below market.
Buyer: Wow, ok. I have a budget of about 460 for a used amplifier.
Seller: Oh my. That's lower than I anticipated. How about $900? Would that work? I'll throw in our remaining Sirius XM membership.
Buyer: The XM offer is great, but that's still way out of my price range. Does it come with any kind of warranty?
Seller: There's about 8 months left on the warranty, which should help you. How about if we meet in the middle somewhere about $725?
Buyer: I could probably pull a little extra money out of savings, although my partner may kill me. I could do 575
Seller: If you can do $650 while still on speaking terms with your partner, it's a deal.
Buyer: Well, you did say it comes with a warranty and the remaining XM membership. So, you've got a deal.
Buyer:
Seller: Sounds Great!
