Buyer: Hello, what condition is you bike mount in?
Seller: It has only been used a few times, so in really great condition still.
Buyer: That sounds good. How long have you had it?
Seller: I have had it just over seven months.
Buyer: Okay. That's not too long. I'd like to buy it from you for $7 since it has been used.
Seller: that is less than half of asking...
Buyer: I realize that but I'm site unseen. For a used object, I think that is fair.
Seller: Well I really do want to make a deal with you , but you need to come up a little in theprice, it is almost brand new.
Buyer: The best I can do is $9 if you're willing to hold it for me for 2 days while I wait for my paycheck.
Seller: I suppose I could do that. 9 sounds fair enough
Buyer: Awesome. Then $9 it is. It was great doing business with you.
