hello. 
Hi, are you interested in buying the chairs?
Yes, I saw your ad online and I was wondering how much you are asking for the chairs
I am asking $50. for all 6. 
I see, thank you.  Can you tell me about how old these chairs are and how long you've had them?
They are around 10 years old but have hardly been used. I bought them new 10 years ago.
thank you, they are beautiful.  Would you be willing to sell the 6 for 45.00?
