Buyer: Cool, is your price fixed or can you come down some?  It's a little out of my price range/
Seller: You can make me an offer if you'd like.  I am pretty firm on the 3000 range, I could come down a tad bit.
Buyer: I have $2280 cash, I could come get it today.
Seller: $2280 is too low.  Could you do more like 2750?

[EX Q]: Seller: Hi, you inquired about the IPAD I have advertised? What questions can I answer for you?
Buyer: How old is it?
Seller: Great question. It is only a year old. I decided to get the next generation. I love to get new gadgets as soon as they come out so every year, I upgrade
Buyer: It's really still in excellent condition?  No scratches or dead pixels? Nothing chipped. No scuffs? Everything functions 100%?
Seller: It is in excellent condition. I usually use my Mac Pro book to do all my work on. The Ipad is just for reading in bed at night until I fall asleep. I have all the original accessories that came with it, plus I have all the latest apps.
Buyer: Last questions:  How long does the battery last when fully charged?
Seller: Now that is why this baby is the bomb. It can go six days or more. I have a battery saver app downloaded, that makes power consumption very low. I have gone over two weeks without charging it but I make sure to charge it once a week so the batteries will last
Buyer: Sounds good.  The only issue I have is that the image on the add is broken.  So I would be forced to take your word 100% on the condition and accuracy of the item.  Will you sell it to me for $150?
Seller: I can assure you that you will not have to take my word for anything. Since we are in the same city I will deliver the product or we can meet up in a public place and you can see it for yourself. I am letting it go for way more than it is worth at $175. Even a refurbished one, which has damage would run you $250 or more in the store. This one is in pristine condition, plus I have over $1000 of software that I purchased on there. 
Buyer: Fair enough.
Buyer: 
Seller: Great doing business with you. Enjoy your IPAD
Seller:
