[Q]: Buyer: Hello
Seller: hello
Buyer: I saw your listing for the flip phone, and was interested in buying it from you. How much has it been used so far?
Seller: It has been previously used for only 3 weeks 
Buyer: That is a reasonable amount of time, do you happen to have a headset or any devices for hands free capabilities to pair with it?
Seller: It's like new, the use on the phone was minimal. The phone is equipped with push to talk (hands free) and accessories with the manual for the phone
Buyer: That sounds good, I'm willing to pay $30 for it, accessories included. Does this sound reasonable for you?
Seller: Accessories are included. Could you do $35? It's listed for $39 currently. 
Buyer: I didn't want to pay too much for a new phone, so I was hoping $30 would be good for you. Would an extra $2 be alright with you?
Seller: Sure, $32 is good with me. 
Buyer: Thank you very much!

[Q]: Buyer: Hi, nice bike.  What is the asking price?
Seller: it's a $1500 bike, but i'm only asking $500 cash
Buyer: Make it 300 and I'll come right over and pick it up
Seller: can't do $300, it's like new - i only got to ride it twice
Buyer: Yeah, but it's a used bike.  Tell you what, if you want the cash I can buy it for 400 out the door
Seller: I can do $450, it's a barely used bike that originally costs $1,500 - they don't depreciate THAT fast
Buyer: I know, but I only have 400.  Is it a deal or not.
Seller: I can't $400, i'll have to keep looking for a buyer
Buyer: ok, i'll go for the 450
Seller: good man, you can pick it up whenever.
