Here is a great idea to get rid of stuff and help others – the Give-Away Weekend (or day, I suppose).
This kind of event takes away all the hassle of a yard sale while challenging folks to "release their stuff".
Ottawa encourages residents to place items that are "give aways" on the curb!

Check out Halifax! They have a "Give Away Weekend" with a focus on recycling, reducing, reusing and holding an environmentally-friendly event. All good things!
