[Q]: Seller: hello
Buyer: Hi!
Seller: this is a great car, i'm the original owner... i'm asking 4000
Buyer: The car looks in good shape. But I think if I keep shopping around I can find it for around 2200, how close can you get to that price?
Seller: i'm willing to negotiate, but 2200 is too low. I was thinking 3400. if you can do cash maybe I can lower
Buyer: I can pay 2400 in cash right now
Seller: If you can do 3100 ill submit the final offer right now, and drive it over to you. do we have a deal?
Buyer: Make it 3000, pay for a mechanic to inspect it and drive it over and we can make the deal.

[Q]: Buyer: Hello. 
Seller: Hello, Thank you for contacting me, As you can see the bike is in pretty good condition, there are a few after market parts I have added, and I will be throwing in a free bike lock.
Buyer: I'd hate to low ball you, but this is for my wife. It's her 30 birthday and she wants to lose weight and exercise. I've only got $70 and it'd mean a lot if you could lower the price. 
Seller: You know what? Id be more then happy to do that for you. Thank you so much for such a simple sales process, Id be more then glad to see someone else get some use out of the thing.

Seller: You have to reboot the iphone and you will see an android logo when the phone reboots.

Seller: No, no scratches or cracked glass, they are new in the box.  Never opened.
Buyer: How much memory?
Seller: 64GB

Seller: I understand that.  The lowest I can go is 550...they are brand new afterall.
Buyer: I understand. Could you throw in some headphones? If you do, I'll go the $550.
