Input: Consider 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:
