I thought I would mention Freecycle.org here. It's a great way to get rid of stuff and acquire things you need at the same time.
I just got a washer and dryer through Freecycle. They're not new, but they work. And all it cost me was paying some friends to pick them up for me.
Through our local freecycle mailing list, there is a lot of baby stuff, I noticed. Sometimes pets are put up, but the group generally disapproves of that. For the most part, people will offer stuff that is too good to get rid of through the trash, but too much trouble to put out for a yard sale.
For those who want things, there are some etiquette rules--don't ask for too much, and not unless you have "balanced" your request with some offers as well.
There are groups scattered all over the country, and all over the world. The main website is at
http://www.freecycle.org and will direct you to local groups in your own area.
Just a few things which have gone through ours lately (other than baby stuff: someone asked for a VCR; someone offered lots of cardboard moving boxes; someone offered a Porsche (not working!); someone requesting small kitchen table; offering of a MAC computer (older model); lots of books; exercise equipment.
I don't know how many are interested, but it's a good way to put a little goodwill into the community in which you are in, and if you have the ability to offer some items as well it will always help someone. I have started to take inventory in my own apartment to see what I don't need, want or have no longer any use for to see what people might be able to use. One guy on the list is a computer techie who takes as many computer parts that are offered, and puts together full computers for freecycle members! No part is too small or too old in order for him to find a use for.
If anyone is interested, or has already been part of Freecycle for awhile, pipe in! I'd love to hear of experiences from others.
