Seller: Hello! How can I help you?
Buyer: Hello I'm interested in your bike. Is it all in working order?
Seller: Yes! It is in excellent original condition my friend!
Buyer: Super, that's great. I'm on a really tight budget and need this to get to work. Is there any way you could go lower, around 175? I could give you all cash today, pick it up myself, if you are available.
Seller: $175.00 is pretty low! I am trying to get a plane ticket to California my Dad just passed away, and I really need the money as low as I am willing to go right now is about $300.00 which will cover my cost. I can also drop this baby off for ya no extra charge.
Buyer: Sorry to hear about your Dad. I just don't have that right now. 225 is as high as I can go. Otherwise I'm out of food for the week. Appreciate you offering to drop it off for me. Will that work?
