Question: Buyer: I'm interested in your powerbank--I'd be willing to pay $9 for it
Seller: You know this power bank is brand-new right? So it's worth $20 and I already lowered the price to $12 so I could sell them quickly.
Buyer: Of course--there are comparable products on the market, inlcuding from amazon, for a similar price
Seller: I made sure to price them below the prices on Amazon. I will go down to $11 final offer.
Buyer: I'm willing to consider $11, are there other perks to this device I should be aware of? I know that it has several protections built in--but I want to make sure
Seller: Yes the battery actually last a long time and it has five security protection.

Question: 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

Question: Buyer: Hey, I am interested in your radar detector.
Seller: It really is a great one, you've found a good deal. Do you have any questions?
Buyer: How long did you own it?
Seller: I have only had it about 6 months
Buyer: Any problems with it?
Seller: No there's nothing wrong with it, I just wanted a newer one.
Buyer: Well, it looks great, but $250 is a bit steep for me. I was looking to pay maybe $210.
Seller: $220 and we've got a deal
Buyer: That's a little bit more than I'd like to spend.
Seller: $215?
Buyer: I see that the case and suction cups and included, so I will take it for $215.
