Dear Craigslist denizens,
No, I will not hold a free couch for you. I will give you the courtesy of letting you know if someone else picks it up before you can so you don't waste a trip out. It's a free couch. I'm sure you can find another.
No, I will not take $120 for this thing I am selling for $350 and which costs $400+ used no matter where you look. No, raising your offer to $125 with the promise of "in cash, today" does not make me more inclined to take you up on it.
Also, I do not care how much you originally paid for your TV four years ago. Four-year-old TVs hold their value about as well as four-year-old milk.
