Buyer: Hello, I am interested in buying your product.
Seller: Great!
Buyer: Will you describe your product to me?
Seller: Sure. It's Fender Champion amplifier. Aside from some slight rust on the corners, it's in great condition.
Buyer: That's good, how long have you had it?
Seller: A couple years, I used it for practice and it has treated me well.
Buyer: That's great. Do you think you could go a little lower on the price?
Seller: I can work with you a little, but I'm hoping to put the money towards some new equipment. I'm willing to knock $5 off if you're willing to pay in cash.
