Question: Buyer: I'm interested in purchasing the mattress you are selling.  Could you tell me something about it?
Seller: Great, I sure can! It is a Serta Twin XL mattress in excellent condition, with box springs and a frame. It's only 2 years old, so you could get many more years of use out of it! I will also be throwing in a set of sheets and a comforter for free.
Buyer: I'm very interested.  I am a starving college student, however, and the $275 is a bit high for me.  Would you consider $225?
Seller: I totally understand. I am pretty strapped for cash since I am moving. I paid a little over $350 for it, so what if we meet in the middle at $250?
Buyer: I'm pretty sure I can hit my brother up for the other $25.  Let's do it for the $250.

Answer: furniture


Question: Buyer: Hi, I'd be interested in your Blu Ray player, but the price seems a little too high. Would you take $25 for it?
Seller: Hi. I will take $40 for it, and pay for shipping. If it quits working within 60 days, I will give you your money back.
Buyer: I'd be willing to offer $30 and will pick up. I'll also pay cash at the time of pickup. I dont need the case either, so you could sell that separately to make a little more money.  I'd do $35 with the free delivery and warrant though.  Either option is ok with me
Seller: 35 sounds good. Free delivery and warranty included. Thank you!
