[Q]: Buyer: Hi can you tell me a little about the bike you are selling?
Seller: It's a vintage, one of a kind. We actually had it assembled by hand with performance parts, it's definitely a special bike for enthusiats. 
Buyer: My son would love this bike! Are you willing to come down on the price at all?
Seller: I'm willing to negotiate, but I don't have too much wiggle room on it.
Buyer: I would like to offer $300, how do you feel about that?
Seller: Can you meet me halfway on the price? $330 and I'll even throw in the spare tire I have for it.
Buyer: At the price of $330 could you drop it off at my house for me?
Seller: Sure, as long as you're local.

[Q]: Seller: Hey there, you're interested in the drum controller?
Buyer: Yes, I'm interested. When did you get it?
Seller: Around a half year ago, it still works great, I tried to get into the drum hobby and stuff for orchestra but got bored alone. You're a DJ?
Buyer: Yeah, just starting up and looking to get some equipment. What condition is it in? 
Seller: Great condition honestly, I think I only used it twice, if you want the manual and original packaging
Buyer: Yeah I'd be interested in those extras. However, considering there's no software included and it will be tough for me to find it, would you consider lowering the price just a little bit?
Seller: Oh, by all means, what's your budget? I don't think I could justify going much lower than 35
Buyer: I think we can work something out. I was originally thinking 35 but since you're throwing in some extras how about 40? 
Seller: 37 for being so obliging
Seller: 
Buyer: 

[A]: electronics


[Q]: Seller: I'm selling this two-person bike. Great quality and good condition. Nice for a bike ride with a friend. 
Buyer: HI, i'm interested in buying your tandem bike. But I think the asking price is a bit high.
Seller: What price range are you thinking of?
Buyer: I'm more at the $525 range.
Seller: I'd prefer not to go below $600
Buyer: $600 is fair, but I can't go that high. Also, there aren't many people who are interested in tandem bikes nowadays, so I feel like the bike may sit for awhile if you don't take my offer.
Seller: True. I'll cut you a deal. How about this, if you ride this bike with me around the block, I'll sell it to you for $500. I never got to properly use it because I have no friends. 
Buyer: Aww, I am more than happy to go for a bike ride with someone with no friends. $500 it is.
Seller: Deal
