[EX Q]: Seller: Hello! I have listed the price of the bike at $3450
Buyer: Hi. I'm wondering if you would be willing to accept a price of around $2000 instead. I'd be willing to pick it up from wherever you have it now.
Seller: I cannot go down that low. I'd be willing to knock it down to 3000, and throw in a bikelock with a custom helmet
Buyer: I'm not sure if I'd be interested in the lock and helmet. In what condition is the bike? I see you've written "brand new" in the description, and I'd be willing to go up to $2500 if the tires are new and the frame and chain are in good condition.

[EX A]: bike

[EX Q]: Buyer: Why are you selling this?
Seller: Hi! I won an iPhone at a BINGO night so I no longer need this item. Otherwise, I would have kept it for years, I'm sure.
Buyer: Congratulations on the BINGO win! As you no longer need it, I feel that $120 is unreasonable. Because, I will also have to get a data plan which will cost more money. I can meet you at a predetermined location set by you. If I like the phone, I will give you $80 cash.
Seller: I'm sorry I can't go that low. I feel that $120 is a very fair price for a phone in this condition, but I will be willing to part with it for $100 if you can pay cash today.
Buyer: Do you have a cover for the phone?
Seller: Yes, I have a like-new otterbox for this phone that I will be happy to throw in at the $100 price.
Buyer: Come down to $95 and you have yourself a deal. I will stay pay cash of course :)

Buyer: 

[EX A]: phone

[EX Q]: Buyer: Can you give me the measurements for the speaker?
Seller: I am sorry, but I am really bad at guessing dimensions. Perhaps you could look it up: JBL Portable Speaker On Stage Micro Audio Speaker System. I will say that it is quite small, but very powerful!
Buyer: And it puts out really good sound?
Seller: Yes! It's hard to believe such big sound comes out of this little bitty speaker, but the sound is loud and crystal clear. I paid $120 for it less than six months ago. My boyfriend just bought a new one and we have no need for this one anymore.
Buyer: It sounds great and I really do want it but, I'm not sure I can do 30. Could you go down 5 or 10 bucks?
Seller: Lowest I can go is $25 . . . and I'll give you four new batteries to put in it :)
Buyer: I think I can do 25. Thank you.
