I'm interested in purchasing the mattress you are selling.  Could you tell me something about it?
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.
I'm very interested.  I am a starving college student, however, and the $275 is a bit high for me.  Would you consider $225?
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?
