Hello you are interested in my deck rockers? 
yes! They are beautiful, do they have any tears, rips, or stains?
No they are in like new condition.  Only used for one season.
Oh great! And I take it the cushions are waterproof?
Yes.  Even though they are coated I still covered them when not in use. 
Okay, and they are rockers? As in rock back and forth?
Yes. They are more of sliding front to back then a traditional rocker. 
Wonderful. Would you be willing to negotiate? Say $135 for both rockers?
I am willing to negotiate.  But I would be looking more at $200 if you take both. 
Oh wow that's $50 more than your listing price. I definitely cannot do that. 
I apologize, I thought you wanted to take two.  They are a set.  I am asking $150 each or 2 for 250.  
Oh goodness, I didn't realize that. yes i would like one. Would you be willing to take $140 for 1?
Yes.  I would take $140 for one. 
Great thanks!
