Input: Buyer: Hello! I am very much interested in purchasing this bike. Do you have it only in blue color?
Seller: Yes, I only have to one bike and it is blue. It was recently painted so there are no defects in the paint
Buyer: Okay, what about the price? Can we negotiate the price because its too expensive for me.
Seller: I'm asking $250 because it was recently painted and has been kept in pristine condition. I'm willing to negotiate a little but I don't have much wiggle room.
Buyer: $250 is a huge amount which I at this point cannot afford nor does it fit my budget.
Seller: What about $235? You also have to remember you're getting the headset in addition to such a great bike.
Buyer: I can give $125. You can remove the headset if it even matters?
Seller: That barely covers the paint job. How about $250 and I throw in a helmet and knee pads that I won't be using.
Buyer: I cannot go beyond $150.
Seller: I'm sorry about the last offer. I meant to say $200. But that's the lowest I can go. If that won't work for you, I'll have to move on to other interested parties.
Buyer: How about $180 and I can come get it from you right away?
Seller: Ok. for $180 that would work.
