Question: Buyer: Hi. I am interested in your iphone. 
Seller: Hey there!
Buyer: The phone appears to have plastic still on it. Has it been used at all?
Seller: Awesome! It's matte black and has 64GB of storage. It's like new, slightly used, but very brief. No marks, dents, scratches, or anything. Good as new. $320 for it.
Buyer: This is a bit high for me. Would you be willing to go lower? I could come pickup myself at $250
Seller: It's a new Iphone 6, you wont find one for $250. $300 is the lowest I'll go i'm sorry. I can deliver it to your place if that makes it any better price wise.

Answer: phone


Question: Buyer: Hey, what can you tell me about this Specialized bike?
Seller: It's hella high grade and expensive.  
Buyer: What do you think about $1000 dollars for it?
Seller: I know the pedals aren't included, but that's really low balling it. I know it's dumb to spend 2450 bucks on a bike, that's why my wife is nagging me to get rid of it. How about $2300
Buyer: $2000 is the highest I'm willing to go. I can come pick it up from you in the next thirty minutes or at your earliest possible convenience and I can pay in full in cash
Seller: Alright, can you take my wife too ?
Buyer: Ha! Ha! Ha! Funny one. I already have enough problems of my own at home with just a dog.
