Julia, just donate it somewhere. Local social services agencies, the local library, Goodwill, Salvation Army, and local charity thrift stores are good places to call. Just call and ask if they can take it, and if they can pick it up.

I work in social services, and our lobby has a "free table" (it's expanded to include a two-level hanging rack and a shelving unit in addition to the original table) where staff and clients can leave or take stuff. This makes it hugely convenient for me to get rid of stuff, and I have some insight into the process. Things don't stay on the table for long. One of three things happens: 1. Someone takes it. This is what happens to the vast majority of stuff that gets donated. 2. It stays for a long time, and then our receptionist culls it and takes it to one of the charity thrift shops. 3. It's deemed unsuitable (used underwear, things with holes or stains, some other miscellaneous such things) and gets thrown away. I dislike number 3, but at least if something I donate gets thrown out for whatever reason, I have the satisfaction of knowing I tried to give it away, and I feel less guilty if it has to go through a second filter before it gets tossed.
