For those readers who may not know about these websites, I figured I'd point you in the direction of a few websites where you can get free or second hand things.
For those that like free things, FreeCycle.Org is a network of different yahoogroups across the globe. Freecycle is dedicated to people giving away things and people claiming things. There is no money exchanged. If you need something, you post to the yahoo group that you're looking for it and people may respond to you and tell you that they have just what you're looking for.
If you want to get rid of some things from your home, even if you think no one might have any use for it, post it to your local freecycle chapter- you'd be surprised who wants a bag of fabric scraps or old toilet paper rolls, or a broken washing machine. I got my refrigerator (working) from freecycle- I just needed to pay someone to transport it.
Go to FreeCycle.org, type in your location, find the yahoo group for your area and sign up for their emails. You'll only benefit.
You probably all know about ebay.com and half.com to purchase things second hand. I felt they deserved a post here anyhow.
Craigslist.com is also a great website when looking to purchase second hand things. Look under your location, type what you're looking for into the search engine and you'll find many people selling the item you need. By keeping an eye out, you can get really great deals this way.
Paperbackswap.com is a great resource for those among us who need books for longer periods of time than the 2 or 3 weeks you can keep things when borrowing them from the library. I haven't tried it yet, but from what I hear, you only need to pay for shipping for the books you are swapping but don't need to pay a cent to purchase the book.
Last but not least, on yahoo groups there are many groups geared towards your hometown. I know that the last 4 places I lived had a yahoo group dedicated to the goings on in the community and it is a great resource for people to find out about free events, advertise things for sale, buy things second hand or borrow things. Search in yahoo groups to see if there is a usergroup for your home.
Do you know of any other worthwhile websites for free or second hand things?
