Hello
Hello, I am interested in your couch for sale.  
Yes I see. Do you have any questions about it?
How bad are the scratches? Are they very noticable?
They are about 4 inches in a few spots. Do you have pets?
No.  I am allergic to cats so I would need to have the loveseat professionally cleaned.  Would you take $40 for it?
You do know you'll have to pick it up yourself and If it's in cash, yes. 
Yes. perfect.
