Buyer: Hi I am interewted in your unlocked Iphone 4 you have selling for $80. Can you tell me some basic fact about it?
Seller: Sure. I have only used the phone for about a month. I decided I wanted a different color, so I got an new phone and I am selling this one.  It works great.  Are you interested?
Buyer: Yes, I am interseted. I will pay $72 for it because I do not think it is worth $80. Is that good?

Seller: hi
Buyer: Hey I am instrested in these speakers can you give me more information on them
Seller: they are new, i want to get rid of them because they don't fit in my car, I got confused with sizes, sound is perfect , it 600 real watt amp, sound is clear
Buyer: Oh ok its says mint condition so how is that new? Anyway I would like to purchase for $120
Seller: I meant to say fairly new because I used them once, 120 is too low, I can go down to 190 final
Buyer: Ok but it doesn't come with an amp which means I would have to buy one 
Seller: yes, i might have one that needs a little repair, I could give that to you if you get it a 190
Buyer: That sounds great do you install as well? 
Seller: no I am sorry, I would'nt want to ruin anything 
Seller: 
Buyer: So can you do $130 since I have to pay for install
