HI. I see that you are interested in the Bike
Hello. Is the bike still available?
Yes I am. How old is the bike?
It was made in 1973. It is a very classic bike. 
Thanks. I see you have it listed for $50. Would you accept $35?
$35 seems a little low. How about I deliver the bike to you for $45?
I will pick it up from you if you sell for $43?
Yea great! I can do $43.
