Buyer: Hello, I am interested in your mattress
Seller: Hi. Great, I still have it. I'm asking $225 for it.
Buyer: How many scratches does the bed have? I think $225 is a little high for a used bed/mattress only in "good" condition
Seller: There are only a few. It still looks pretty good.
Buyer: Would you take $150? The mattress has been used for many years and I'm not sure I'm comfortable paying so much for furniture that has been used tht much
Seller: How about $200 and it's yours.
Buyer: Will you deliver it too?
Seller: For $200, I can get my buddy to drive it over in his truck. Are you local?
Buyer: Yes I am. Deal!
Buyer:
