Hello
Hi! You're interested in the sofa set?
Yes I am. Is it in good condition?
It's brand new! Still has the tags and everything. Turns out it did not match the decor at all!
How much are you charging for it?
Listed it for $1000, but willing to negotiate. What price were you thinking?
I was hoping to pay around 500 dollars for it.
That's a pretty steep markdown. We're looking at a 3 piece sofa set, new, leather. That's definitely worth more than $500. 
How about 700 and I will pick it up myself?
That would work perfectly! Sounds like a deal.
