Before tossing, think! Can the item be re-purposed another way? Can you turn that old wooden CD holder into a chic wall shelving unit by turning it on it's side and slapping a fresh coat of VOC paint on it? Can that old jacket be donated? Kevin and I found beautiful old french windows someone was tossing, we cleaned them up and hung them on the wall. They are fire engine red and our favorite find!
Stop cleaning out without thinking first, someone can always benefit.
Here are some ideas on what to do with your goods:
Craigslist - list your items for cash!
Ebay - I'm no stranger to selling (and buying) on ebay, it's a great way to get some green for your stuff
Amazon - Sell old books and cds with ease (among other things!)
Freecycle.org- where you exchange items free of charge
Consignment shops- because that old suit could be worth something!
Charity- there are many organizations that take donations, salvation army and goodwill to name a few...
