Craigslist
While Craigslist is a place to buy and sell stuff, there is also a free section where people put up stuff to be taken away for free. The main reason is that they just want to get rid of the old stuff (not literally old sometimes its stuff they don’t use anymore) and instead of putting efforts into garage sale is not on their list they place it online so people come in person and pick up their stuff on their own expense. Things like washers and dryers, furniture and clothes all that people wish to move out of their homes for free.
The important point to keep in mind here is only a local listing will work for you since it’s unlikely you’ll travel all the way to just claim a sofa given away for free, you probably can’t transport a thing so big from a far fetched area.
Freecycle
This website contains stuff that is in working condition but was found out of a dumpster. People throw lots of stuff away just like that at landfill sites because they don’t need it anymore and the website made a good use of such piles found outside the landfills or dumpsters.
But point number one: you need to be quick as they operate on first come first served basis and point number two: you just can’t always grab stuff from them, you are required to give back too or consider your membership gone for good.
eBay Classified
like craigslist they have a free stuff section you can look into to find sometimes pretty useful things.
A website that deals with only free stuff so usually no shipping services can be seen on the website as people visit in person the places from where the free stuff is offered and pick those up themselves.
BarterQuest
This one is a great website that uses a different concept. People can swap stuff and services here. So money is not always the payment method they remind us pretty cleverly.
