[Q]: Seller: Hello
Buyer: Hi
Seller: Are you interested in the bike I had for sale?
Buyer: Yes, I see it has some issues with the brake
Seller: Yea, it has some minor issues, pretty easy fix. I have just moved on to other projects and was wanting to get it out of my way.
Buyer: I will give you $150 for it
Seller: Ah, that's a bit low for all the custom parts and stuff I have on the bike. Tell you what, you come get it today, cash in hand, you can take it for 200.
Buyer: I can do that for 175
Seller: Nah, I already knocked off 100 bucks off the price. At this point I am losing money. 200 bucks in really my bottom dollar.
Buyer: I can't offer any more than 180
Seller: Cash today?
Buyer: Yes
Seller: Deal

[Q]: Buyer: hi there looking for a mazda
Seller: I have a great 07 CX-9
Buyer: indeed i see that you did all these great things to it. it seems to be in good condition. i am willing to pay 6000
Seller: 6000 seems a little low, I was originally asking 8k but after I had to have the brakes and rotors replace along with the other maintenance I had to raise the price. 
Buyer: the car is a bit old and it has very high mileage. I see that it has been taking care of however. Look my best offer is 7000k.
Seller: Age is not as big a factor as care taken. Miles were put on consistently over the years, oil changed every 3,000 by myself with premium grade oil and filter from the dealer. Lowest I could walk away with is 8200. There aren't too many other vehicles out there in this condition that low.
Buyer: I am afraid that we can't deal then.
Buyer:

[Q]: Buyer: hello
Seller: Hello. Are you interested in our services?
Buyer: Yes I am
Seller: Ok. We charge $50 for unlocking and flashing phone devices. 
Buyer: That much. Are you willing to discount the price for first time customers
Seller: For first time customers we offer a price of $45 for the service.
Buyer: That's still pretty steep..Hmm what about 35.00? 
Seller: Sorry, I can not go that low. The best I could do is $45 and have the device back to you within 30 minutes.
Seller: 
Buyer: What other services do I get with 45.00?
Seller: There are no other services? We unlock and flash phones to remove them from the network--that's what we do.
Buyer: If you are flashing my phone I still have to pay for first month service. You are not losing anything with 35.00. I still have to pay for first month service.
Seller: I can make you a final offer of $45 to which you can accept or reject. Sorry, our prices are firm. 
Buyer: Do I get a free phone case with it? What about 40.00?
Seller: I do not see us reaching an agreement here. 
Seller:
