Hi, I'm interested in the couch you have for sale
Great!
It looks like a great couch but the price is rather high for me.
Well,it is unbelievably comfortable.It just clashed with my other furniture.I can maybe go down a little?
I was hoping to pay maybe half if possible, ideally. That seems like a good price for a used couch.
I wouldn't call it used.I think it was sat on twice so the price listed is practically a steal!How about $950?
Hmm. I could go $600, how about that? By the way is the couch easy to disassemble, or does it have to be moved intact? I'm thinking about how easily it could be transported.
Hello, Do you have any interest in my couch for sale?
Yes, I think it is a quite attractive couch, although that is a lot of money for me right now. I was hoping to pay maybe half of what you're asking--what do you think? 
You are right about it being attractive! Give me a price and I will see what I can do.
Well, how about $500? I know it's much less than you are asking for, but I'd be giving it a great home!
I'd love for it to have a great home, but I need to have a home too! LoL! How about $850?
Oh, we're definitely moving in the right direction! That's still a bit steep for me but...well...I really like that it is made from largely recycled materials. How about $600? By the way can this couch be easily dissasembled for transport? If not I'm probably going to have to rent a small moving truck. 
Tell you what. I will deliver it to you assembled at no extra charge.Plus, I'll even throw in two free throw pillows all for $825.Oh yes, it is made from recycled materials.That is a wonderful thing!
Thanks for offering to deliver it assembled if we can come to an agreement--that will make it much easier on my end. It's still a bit pricey for me. How about $725?
If you factor in the price of a moving truck with my offer it is a steal!You'd be paying less with my deal,but since I feel you truly love this couch I will drop it down to $800 and still provide my additional services!
Well...that is more than I can comfortably pay but it is a very attractive couch and since you're offering to set it up, I will accept your offer of $800. 
Great! You won't be sorry. Let's get this transaction started! Thank you!
