Q: Buyer: howdy partner. that's an interesting receiver
Seller: Hello I have a wonderful piece of stereo equipment here for you and it's a great deal at 100?
Buyer: eh, i've seen similar for lower price. it's only 80W?
Seller: Yes it is a 80 watt, I am authorized to negotiate some but I can't go too low or my sale won't be approved, what are you willing to offer?
Buyer: i see. well seeing as how 400W is about 150. and this being 80W, i'll probably do 80 bucks for this?
