Hello
Hi there. How can I help you?
I'm interested in your sound system. Does the remote work?
Yes the remote works very well, and its a great piece of equipment to have. 
I'm not so sure if I know how to hook it up. Is it difficult? Could you show me how if i bought it?
Yes for sure I can do that! I can even send you paper instructions with it to help you do that
Oh that would be helpful. Well how about $100? It's pretty old and doesn't even have an input for mp3s
Well my friend, this instrument is old but its an asset. Its something which was very well worth it. I can give it to you for 150 
I understand, and I'm definitely interested as I still have many CDs. Would you be able to take $120 cash if I come and pick it up?
Okay I guess I could do that.Would you pay cash or credit?
