Hello, I'm interested in the bike. Can we do $25 and I'll come get it right now?
I can give it to you for $45 and throw in a warranty for 6 months
I don't need a warranty. How about 35 and I'll still come and get it.
Lets meet in the middle I'll still give you the warranty and you can come get it for 40
I'll do 40 but you have to bring it to me?
Okay we can do that. So 40 it is
