If you've moved recently, you can feel the pain that San Francisco-based BoxCycle is trying to solve for. It's generally expensive (and wasteful) to buy new boxes and kind of a hassle to hunt them down from grocery stores. After you move, you're stuck with a bunch of boxes to get rid of. Most are recycled but still there is a better way: create a marketplace for people to sell their used boxes to those in need. An excellent idea that I'm looking forward to trying out next time I'm need of boxes. I love ideas that are both eco-friendly and add convenience while saving time and money for the consumer.
