[Q]: Buyer: whoa glitchy system
Seller: Hi, are you interested in the bike?
Buyer: yes. but it's kinda pricey for a 27 yr old bike. 
Seller: I know, but this is a collector's bike.  So people generally fix them up and only ride the bike to show off.  It's actually worth quite a bit because it is so old, yet in decent condition.
Buyer: needing a handbrake isn't in a decent condition. tell you what. i'll give you 100 for it. 
Seller: How about if I throw in a hand brake and you can install it yourself for $150?
Buyer: yeah that's not gonna work for me. 110 is the max i'd pay for a bike in this condition
Seller: Is there something else I can throw in to sweeten the deal?
Buyer: nah. 110, bike and the handbrake. if that's ok we got a deal 
Seller: Okay deal.

[Q]: Buyer: I am interested in buying the Sealy Plush Mattress you have listed. What are the dimensions on the mattress?
Seller: This twin size mattress is 38" wide and 75" long.
Buyer: Perfect. Why are you selling the mattress?
Seller: It was my child's bed, but he's outgrown it! We used it for about two and a half years, but it was covered with protective waterproof sheets, so it is still in excellent shape.
Buyer: Well, my husband and I are new foster parents. We have almost everything ready, but are still looking for a mattress. I think this would be a good fit and complete the room for the kiddos. Are you willing to take $100 for the mattress?
Seller: Congratulations to you and your husband! $100 seems like a fair deal to me.
Buyer: Thank you so much. I am submitting the offer right now. We appreciate your help!
Seller: Thank you!

[Q]: Buyer: Hello!
Seller: Hello - Are you interested in the drink center
Buyer: Yes I am, I'm making myself a little home bar, and this definitely looks like it would fit perfect with the theme I'm going for. I wanted to shave a little off the price though, I was thinking around $35. I could come pick it up myself to save you the hassle as well.
Seller: 35 sounds good if you would be willing to meet me in Fremont. I work in Fremont so I can meet you around lunch time tomorrow if that works for you
Buyer: That works for me, send me the address and I'll swoop by when it's convenient for you.
