Hello. Are you interested in the bike I have for sale?
Yes! I was really hoping to stay under $200, though. But I would be willing to pay more if you could deliver it for me. 
I can deliver it to you, but I can't go that low. I'm a college student, and the whole reason I'm selling the bike is because I really need the money. I'm willing to go as low as $280 because it is handmade, and i will deliver it to you.
The most I can do is $260 if you have a letter of authenticity. I am a collector and the most I've seen them go for with paperwork is $260.
