If it’s not needed or wanted then you probably want to get rid of it. A common problem is that sometimes you just don’t know the best way to go about doing that. Here’s a site that might help. And it’s highly entertaining, too.

And for physical “stuff” you want or want rid of, there’s always http://www.freecycle.org
Don’t mention money and don’t mention swapping, or barter, as those have tax implications, and freecycle.org might be held liable by the IRS as the vendor.
I already got rid of my mental health as a result of this site (http://www.getridofthings.com/, not freecycle.org)! :-)
