Buyer: HI I am really interested in your theater seats for my home theater. How long have you owned them?
Seller: Only two weeks. My stupid wife decided she hated the colors, so we had to get a new set of cream white chairs in the exact same style. We only got to use these once >:(
Buyer: Haha. Sorry about that! So I am guessing then that they are in excellent shape?
Seller: Yes, they're practically new.
Buyer: Great, would you take 1600 for them if I pick them up? I have cash.
Seller: If you're willing to go up to $1700 I'll deliver them myself today. If you'll go up to $1800 I'll throw in the wife too.
Buyer: Well That is a great offer but I don't need a wife, love your sense of humor! I will take them for 1700 and am thrilled you can deliver them. See you later today!
Seller: Okay, I'll be by your house tonight :)
