[EX Q]: Buyer: Can you give me the measurements for the speaker?
Seller: I am sorry, but I am really bad at guessing dimensions. Perhaps you could look it up: JBL Portable Speaker On Stage Micro Audio Speaker System. I will say that it is quite small, but very powerful!
Buyer: And it puts out really good sound?
Seller: Yes! It's hard to believe such big sound comes out of this little bitty speaker, but the sound is loud and crystal clear. I paid $120 for it less than six months ago. My boyfriend just bought a new one and we have no need for this one anymore.
Buyer: It sounds great and I really do want it but, I'm not sure I can do 30. Could you go down 5 or 10 bucks?
Seller: Lowest I can go is $25 . . . and I'll give you four new batteries to put in it :)
Buyer: I think I can do 25. Thank you.
