Sometimes it's easier to sell stuff than give it away.

4. We had the same experience with a mattress & a piano

The mattress was still in good condition. I posted it on Craigslist for free and included several pictures and had zero takers for days. I relisted it for $20 and sold it before the end of the day.

Had the same experience with an old upright piano. No takers for days, then listed it for $25 and again it sold right away.

However, when we do "curb alerts" for items we can put out by the street (old rusted swing sets, yard bench with rotting wood, etc.), it's amazing to see how fast the stuff goes.
