Buyer: Was this used by an adult or a child?
Seller: It was supposed to be for a child but she decided to take up the saxaphone instead so it has been mostly stored away.
Buyer: I can do $275 for it. 
Seller: It comes with a lot of extras so I would like at least 300 for it.
Buyer: Okay would you deliver it for that price?

Seller: Hello
Buyer: Hello
Seller: I'm selling a wooden full sized Futon with 2 slip covers for $125. I take it you are interested?
Buyer: Yes, I am.  I'd like to make an offer of $75 and I will pick up the item.
Seller: $75 is too low. I just bought this item and haven't even used it. The reason I am selling it is that it doesn't fit in the area that I wanted to put it. I'll throw in some brand new pillows and I'll deliver it to your place for $125
Buyer: I am willing to go to $90 because it is a used couch, and I cannot see what the futon looks like completely as it is covered in the photo presented.  I'd be willing to skip out on the slip covers and I do not need any pillows.  I am still able to pick up at this price.
Seller: I'll go for that. You come get it where it is located at an amazing price of $90!
