Seller: Hello I have a wonderful piece of stereo equipment here for you and it's a great deal at 100?
Buyer: eh, i've seen similar for lower price. it's only 80W? 
Seller: Yes it is a 80 watt, I am authorized to negotiate some but I can't go too low or my sale won't be approved, what are you willing to offer?
Buyer: i see. well seeing as how 400W is about 150. and this being 80W, i'll probably do 80 bucks for this? 
Seller: That seems fair to me and I think that my boss will approve this price.
Buyer: ok then 80 it is 
Buyer: 
Seller: 

Example Output: electronics

Example Input: Buyer: Hello!
Seller: Hi
Buyer: I saw your listing for the track bike, there wasn't too much detail, but how does it ride overall? I'm looking for something reliable.
Seller: It rides great. It's in excellent shape and you really can't do any better in terms of reliability than a Canondale
Buyer: Sounds great, I was hoping to shave a bit of cash off the price, would you be willing to go down to around $420?
Seller: That's a bit low from what I was looking to get. If you're willing to pick it up to save me the hassle of shipping, I could let it go for $525
Buyer: Thats pretty fair, I could definitely pull the trigger on that if you dropped it down to $500. The location is a bit far out, but I wouldn't mind making the trip.
Seller: Ok, I think $500 is a fair price.
Buyer: Great! Thank you very much.

Example Input: Buyer: hi 
Seller: Hello.
Buyer: how many colorsw do you have
Seller: They are all black. We got them as company phones so all are the same. But brand new and unopened.
Buyer: tell me a little about the features
Seller: Sadly I'm not a phone salesman but it's easy to find the information about Samsung S8 online. It's the newest model, fantastic camera, resolution and great quality. As I said, brand new, in original box. You won't find a better offer anywhere.
Buyer: great can you let me get it for 550 please i need a good phone for my wife
Seller: I can't lower the price much if you are only buying one. Discount offers is for those willing to buy multiple phones. If you are really looking for a gift for your wife I might go down slightly, but in that case you will need to pick it up yourself. 600 dollars if you can pick it up yourself.
Buyer: all i have is 598 can u work with that ill pick it up
Seller: Alright, we can agree on that.
Seller: 
Buyer:
