Ex Input:
Buyer: Hello
Seller: Hi how are you?
Buyer: Good. I am in the market for a new bike. Is this one in good shape?
Seller: This one is in fantastic shape! It's got some great options too. It has a step thu frame, cantilever brakes and a shimano drivetrain.
Buyer: That sounds awesome. How much do you want for it?
Seller: I'm asking $350 for it, but I'm willing to negotiate, especially for cash.
Buyer: Would you be willing to lower the price down to 250? I will pick it up myself.
Seller: Sorry, 250 is too low. I'll deliver it myself for $300, and we have a deal.
Buyer: That sounds good to me. Nice doing business with you.

Ex Input:
Buyer: Hi, I'm interested in your bike. It's a little larger than I'm looking for, but I like the style. Would you consider accepting $150?
Seller: Hello, do you have any questions about the Bike?
Buyer: Will you sell this for $150?
Seller: No, I am willing to negotiate but that is too low. Do you have any questions about the bike? It is really in good condition.
Buyer: I think the price is a little high, I can buy a 21-speed new for $350, and that includes a warranty. What about $165?
Seller: You haven't even asked any questions about the bike. If you had you would know that it has CST 700X38C hybrid tires, Schraeder valves, Rear Shimano Altus derailleur with MegaPulleys... and many other great feaures. So, as you can see this bike has many great upgrades making it fully worth the asking price of $200..
Buyer: I'm familiar with this model of bike, my brother had one just like it. You didn't mention those upgrades in your listing though, that does add a little value to it. I'm still not sure that it's worth quite $200 though considering what I can buy new for a similar price. I'd be willing to raise my offer to $150.
Seller: That is why I kept asking if you had any questions. I'm a bit concerned you're just a reseller looking to undercut other buyers and then make a profit. If you want a new bike without all these great upgrades you should definitely get one. But all things considered I think I'd better not accept such low offers right now. I can go $195.

Ex Input:
Buyer: Hello, I am interested but the price seems extremely high for this neighborhood and only 1 bedroom I would be willing to pay $850
Seller: What? It's Berkely. California is expensive, especially this area. I'm willing to do $1600. If you notice we are very selective and don't allow section 8. Your neighbors are upstanding people.
Buyer: The same size units are going for around $900, that is what I would offer you.
Seller: No, you need to meet me int he middle at $1250.
Buyer: I cannot go higher than 1,115. That is more than fair when you look at the comps
Seller: Ok, but can you do first, last, and security deposit at once?
Buyer: Sure, that would be fine.
