Seller: Hi! I am willing to sell this bike at a great price are you interested?
Buyer: Yes, I am very interested! It looks like a beautiful bike.
Seller: Ok cool! The bike has very low miles and has and upgraded WTB saddle! It also has carbon blade forks and 105 brakes. I am willing to sell for as low as $750.
Buyer: $750 seems a little steep since the bike already has some miles on it. Would you accept $400?
Seller: $595 is the lowest for a fact!
Buyer: $595 is a little high for my budget. Are there any accessories you'd be willing to throw in--for instance, a basket, lights, and/or bike pump? That would make it a lot more appealing for me.
Seller: I will throw in my 700c wheelset, instead of the standard wheelset. How about that!
Buyer: I am excited for the 700c wheelset, but it looks like that was already listed in the ad. Is there anything else you can include?
Seller: Nothing unfortunately. How about 550 and we can call it a night!
Buyer: That sounds pretty reasonable. Before we make the final agreement, could you just let me know roughly how may miles are on the bike?
Seller: Well I bought the bike from someone else and have not used it. He did not specify on the miles but just said that it was very low!
Buyer: Hmm--the ad says that you bought it new. Since you actually bought it (lightly) used from someone else, can we lower the price to $450?
Seller: Sounds good!
