Following this gift-giving season, many of us probably have a boatload of cardboard shipping boxes lying around. Instead of breaking them down and tossing them into the recycling, there's an easy way for you to put them to good use.

An organization called Give Back Box works together with charities to set up the following system: You take your empty shipping box, load it up with stuff you no longer want and that you'd like to donate to a charity, then you go to GBB's website to print out a prepaid shipping label to that charity. Then all you've got to do is drop the box off at a post office or UPS center (or order a pickup online) and boom, the box is being used again, and you've gotten rid of some unwanted stuff that someone else could use.
