Buyer: I like the bike, but it is 37 years old. Is there some wiggle room on the price?
Seller: I know the age seems to be a factor but it is an original, I have taking care of this bike for many years and it is great for anyone who enjoys bike riding. I can listen to a few offers but be reasonable please.
Buyer: I could go $675
Seller: Your paying for a piece of history can you at least do $975.
Buyer: I could go $725 if you could deliver it/Ship it
Seller: well that is gonna cost me some money to deliver it to you. This bike has tradition and has all the original decals are still on it. It has new tubes and I even throw in a warranty.
Buyer: I can do $850, it's literally all i have for this purchase.
Seller: I can do at least $933 and give you the warranty, deliver it and even throw in an extra tire with rim.

bike

Seller: Hello
Buyer: Hello, what can you tell me about this item?
Seller: I'm selling a GoPro Hero 3 black edition with a waterproof case. It has an 8g memory stick and the charging cable. It is in excellent condition and works perfectly!
Buyer: Does it come with the original box?
Seller: Sure does! I didn't really use it much. I've only had it for a few months.
Buyer: What are you asking for it?
Seller: Well, they retail for around $379. It is slightly used so I'm asking for $130
Buyer: Will you deliver it?
Seller: Yes. The $130 includes shipping!
Buyer: I will pay you 98 for it and I will come pick it up.  Since it doesn't come with a warranty I dont want to risk paying to much.
Seller: Hmm, 98 is a bit too low for me. I'm looking to get back some of my money here. The item is basically brand new. How about $120?
Buyer: will you throw in a warranty with it?
Seller: It's still under warranty. I've only had it for 3 months and I believe the warranty is good for 2 years.
Buyer: Ok deal

electronics

Seller: Hi, are you interested in buying my AV Pre-apmlifier?
Buyer: Yes, how old is this amp?
Seller: I've only had it about 6 months, it is still like brand new in mint condition.
Buyer: did you not like it?
Seller: Unfortunately I lost my job so I am needing to sell some things. I love the amp and hate to get rid of it, but I need to pay rent.
Buyer: I am sorry to hear that, life is unfair sometimes.
Seller: Yeah, but it is a great amp and a steal at this price.
Buyer: Honestly I was hoping to cut a deal with you, I can pay $875. I am on a budget myself...
Seller: If you could go up to $900 I will deliver it to you tonight.
Buyer: Ok, I think we can agree on $900.
Buyer: 
Seller: Awesome I appreciate that, thanks!
