Example Input: Buyer: Hello I'm very interested in purchasing your Galaxy S8
Seller: It is a beautiful phone.  I stupidly purchased it for a former lover, but you know what they say, nothing is permanent. I paid $900, so this is a huge loss.
Buyer: I have about $675 cash  that I'm willing to offer. Can I also add my current phone with the $675 cash? If you sell my phone you'll make enough for what you're asking. I can also drive to you and save you on gas money!
Seller: Wow! Wha is your current phone. I think this is a definite possibility so long as there are no cracks in the screen and it has a clean esn.
Buyer: It's a galaxy S7. I have it paid off so you can jailbreak it to whatever carrier you need. I am the only owner of this phone, I can meet you at a Tmobile carrier to verify that.
Seller: Sounds like a plan. I accept that offer,
Buyer: 
Buyer: Thanks!
Seller:

Example Input: Seller: Hey there! Heard you were interested in purchasing my Marin Coast Trail bike
Buyer: how old are the tires?
Seller: Got them changed two months ago, they're 26 x 1.95 inch Kenda Krossplus tires
Buyer: Was there a chain guard with the bike?
Seller: No there isn't, she's an older gal. 
Buyer: Would you do fifty?
Seller: I was planning on selling it for around $150, used to ride a lot and kept the bike well maintained. New job and everything so haven't really had the chance to ride anymore. Since the chain guard is missing I'd be happy to go down to $100
Buyer: It would be just parts for me, $50 is all it is worth to me.
Seller: Eh afraid I can't do that. If you'd come pick it up I'd do $75 to save myself the hassle
Buyer: OK, I can pick it up. $75.00
Seller:
