[EX Q]: Buyer: Hi, so I'm very interested in the bike but I must ask is anything wrong with it?
Seller: This bike is like a member of the family....very well taken care of.  It's beautiful.
Buyer: Yeah I agree. The bike looks great. Perfect for my 7 year old to learn on and probbably break his arm on. Are you willing to deliver the bike? Or do I need to come pick it up?
Seller: If you will take it at $850, I can deliver it.
Buyer: $850 is a little too high for me, I can do $800 and I come pick it up from you today.
Seller: I actually almost resended the offer when you stated it was going to be for a 7 yr old.  Its a beautiful antique!  I can't budge on the price.  It's hard enough to let go of as is...
Buyer: Lol it being an antique has nothing to do with it, it's still a bicycle. It's not like I'm going to put it on a pedistool just so I can look at it. Bikes are made to be ridden. Whatever I'll give you 850

[EX Q]: Seller: Hey there, you're interested in my nice bike?
Buyer: I like that bike, but am on a budget. Not sure if you are negotiating today?
Seller: I am always negotiating, my friend. I'd like to make back the cost of the bike, so the bottom floor is 2100. What's your budget?
Buyer: What I am working with today is $1250, is there anything wrong with the bike, how old is it?
Seller: It's about 5 months old, I build bikes as a side hobby. To be fair the bike would cost 5000 retail, which means 1250 isn't really approachable unfortunately.
Buyer: I know, well would you consider 1800 if can give you cash by tomorrow, and pick it up?
Seller: 
Buyer: 
Seller: Sounds good

[EX Q]: Seller: Would you like to buy a Ballistic iPhone 5 Hard Case?
Buyer: Hi does this case come with a glass protection 
Seller: Yes, it has a built in screen protector. Just $5
Buyer: Will my phone break at all with this? And can you do $3
Seller: No, your phone will be safe with this. I think $4.25 is more than fair.
Buyer: I mean they don't make iPhone 5 anymore and I really like this particular phone and don't want it to break 
Seller: I can understand that. It's a very hard case, very durable. It's also shock-absorbent in case you drop it. This thing will definitely protect your phone, very little risk of breaking. $4.25
Buyer: Will it protect in water? 
Seller: Yes, it has a water resistant mesh that will even protect the speakers. It also has button  & port covers on the case. Want it?
Buyer: Yes I do want it but I honestly only have $3 and I think I'm doing you a favor by getting this off your hands
Seller: It is an older case, but there are still a lot of iPhone 5's out there. This case is in new condition as well. $3.00 is just too low. what about $4?
Buyer: Amazon actually has this same case for a $1 i was just instrested in your case because of the color
Seller: It is a lovely shade of blue. The lowest I can possibly go is $4. That's less than a sandwich around these parts.
Buyer: I'm asking you to kindly take $2 off...its just $2 i
Buyer: 
Seller:
