Ex Input:
Buyer: Hi I'm interested in your bike.
Seller: Hello. It's a great bike. It's a collectible. I'm wanting $180 for it.
Buyer: Ok, but I'm worried about the rust, do you know if it's gone through the frame?
Seller: No, it's purely cosmetic. A fresh coat of paint will fix that right up for you.
Buyer: Well it's a little more work than I care to take on. I'd like to get it for $90. I'm probably going to have to take it to a restorer.
Seller: It really won't need much work at all but I do have some wiggle room. $90 is just too low for the collector's item. I could take $160 for it.
Buyer: I'll bring my offer up to $110 but do you have a helmet I could have. Safety first and all that.
Seller: Ok. I'll take $110 for and throw in the helmet.

Ex Input:
Buyer: Hi do you still have the iphone 6
Seller: hello yes its still available its unlocked and like new condition
Buyer: well I can really only pay 140 for it. They are only like 230 at walmart.
Seller: I understand but $140 is much too low. I would be willing to accept $275
Buyer: So your willing to accept more than the cost of a new one for your used phone I can't say I would blame you. Does it come with anything. I mean that is really high for this phone.
Seller: it is unlocked so it gives you freedom to choose any carrier. I think the price is fair. I would take $225
Buyer: Well I will go up to 200 but that is as far as I can go.

Ex Input:
Buyer: Hello... is this a drone?
Seller: No sorry, it is a remote control helicopter. It is very precise and flies like a dream though.
Buyer: Darn. I was really looking for a drone. Could I attach a camera to this and make it like a drone? All my new friends have drones, and man-buns and fidget spinners and I don't have any of that...
Seller: lol, it has an lcd screen on the remote, so it's much like a drone. That way you can fit in with all of your friends.
Buyer: Alright, that sounds great. I still have to buy a fidget spinner though and those things are expensive... would you consider coming down on your price...
Seller: I could do 80 and throw in a clip on man bun.
Buyer: Oh wow.. that is the best offer I've heard all day. Deal.
