[Q]: Seller: Hi, are you interested in the phone?
Buyer: hi i can pay you 120 
Seller: That is too low for an unlocked phone in great condition.  I can lower the price to $300, but that is the best I can do.  I need the money from this phone to buy some other things.
Buyer: I see it is has some condition issues  and it is used  not to mention on the smaller side as far as memory goes
Seller: The issue is cosmetic.  I can bring the price down to $275 if that bothers so.  I can also throw in a free headset.  Deal?
Buyer: i can do 150 thats pretty much the best i can do  275 is still to much
Seller: I cannot sell it that low.  Do you have anything else you can give me plus the money to see if we can make a deal?
Buyer: i can send you an older fitbit  and bring the cash offer up to 175  that is my best and final 
Seller: If you can pay $200.  I will take the cash and fitbit.  I will still give you the headset for free.  Deal?
Buyer: I can do 190 and the fitbit you include the headset  and we have a deal
Seller:
