[Q]: Seller: Hey, you're interested in the bike?
Buyer: I am. My husband an I have been trying to get a tandem for awhile now. We sold our last one when we had kids, now that they are older, we can get back into it. How is the condition? Are you the original owner? Is it road ready? 
Seller: Yeah, this is a spare we kept in a storage unit, and we haven't been on the road in a while. It's definitely road ready.
Buyer: We know our tandem bikes and comps in the area put this one around $135. Would you take that if I picked it up? 
Seller: Oh wow you two have shopped around? Really want it then, 135 is fair. Let's do it.

[Q]: Seller: Hello
Buyer: Hello
Seller: I'm selling a wooden full sized Futon with 2 slip covers for $125. I take it you are interested?
Buyer: Yes, I am.  I'd like to make an offer of $75 and I will pick up the item.
Seller: $75 is too low. I just bought this item and haven't even used it. The reason I am selling it is that it doesn't fit in the area that I wanted to put it. I'll throw in some brand new pillows and I'll deliver it to your place for $125
Buyer: I am willing to go to $90 because it is a used couch, and I cannot see what the futon looks like completely as it is covered in the photo presented.  I'd be willing to skip out on the slip covers and I do not need any pillows.  I am still able to pick up at this price.
Seller: I'll go for that. You come get it where it is located at an amazing price of $90!

[Q]: Seller: Hello how are you?  I am asking 500 but am willing to negotiate some as long as you aren't a low baller
Buyer: I am good. What condition is the MacBook in. Does it have any scratches?
Seller: The MacBook is in great condition because I never used it very much.  There are some tiny scratches but I have an extended warranty on it, so that's very valuable right!?
Buyer: I am willing to pick it up today and pay in cash. Would you take $350 for it
Seller: If you're able to say 380 then you will have yourself a deal?
Buyer: Okay and does that include the warranty?
Seller: Of course yes, and thank you for negotiating!
