Hi! I'm interested in your cabinet but the 'structurally sound' condition doesn't sound too promising. Is it in pretty rough shape?
No that just means it is in good shape. You can shake it pretty well and it won't break. It is nice. If you want it, and I deliver it to your place personally, would you be willing to give me $40 for it?
I think that's too high for used furniture, especially a small piece. I'd go for $20 and I'll pick it up. 
I can't go that low. I paid much more for it originally, and it is still in good condition. I can go $35.
Sorry! No deal
I think it's a great deal. $30 is my lowest, but that's it.
Hmm. I can do $30 if you drop it off as originally proposed. 
Sure thing.
