[Q]: Seller: Hello are you interested in my subs?
Buyer: Yes I am interested how good is the bass response on theses subs?
Seller: The Bass response is excellent, some of the best I've heard
Buyer: I'm looking for something with a punch but I don't want it to shake my car apart or blow up my trunk.
Seller: I think these would work well for you
Buyer: Does it come with all the standard installation parts?
Seller: They are new, still sealed in the box
Buyer: Ok I can personally pick these subs up today with 152 in cash would that be an offer you are interested in?
Seller: No, I couldn't go that low.
Buyer: Then is there anything you could offer to sweeten the deal a little?
Seller: I could assist in installation
Buyer: No im pretty adept at installation do you happen to have any dynamatt or other sound insulation material?
Seller: I do have a roughly 3x3 piece of dynamatt that I could throw in
Buyer: ok that could push me to 172?
Seller: I would be willing to go to 180
Buyer: Could you meet me halfway for that price?

[Q]: Buyer: Hi do you still have the iphone 6
Seller: hello yes its still available its unlocked and like new condition
Buyer: well I can really only pay 140 for it.  They are only like 230 at walmart.
Seller: I understand but $140 is much too low. I would be willing to accept $275
Buyer: So your willing to accept more than the cost of a new one for your used phone I can't say I would blame you.  Does it come with anything.  I mean that is really high for this phone.
Seller: it is unlocked so it gives you freedom to choose any carrier. I think the price is fair. I would take $225
Buyer: Well I will go up to 200 but that is as far as I can go.

[Q]: Buyer: Hi!  I saw your advertisement for an iPhone Case.  Gotta ask the obvious question, are you getting rid of the case because you dropped your phone and it broke?
Seller: Nope, brand new
Buyer: Oh, well that's good.
Seller: Yeah, I purchased the case for $40 but never used it then got the new iPhone 7 
Buyer: Go figure.  I haven't purchased the phone yet, but I drop things and want to get a case for right when I buy it.  Maybe I should just get the 7...
Seller: Yeah, it's a good phone. Bigger screen but not much different than the 6S.
Buyer: Maybe I will do that.  I could still buy your case, but I guess I wouldn't have much of a use for it.  Maybe if you're willing to let it go for $15 or $16, I could buy it just in case I get to the Apple store and decide on the 6s...
Seller: How about $18?
Buyer: Yeah, that works for me!
Seller:
