go to storage units in your area and find out when theyre going to have auctions, you bid on a storage unit, they usually go for like 50$ depending on whats in them, and then you can sell them on here or at a flea market, i prefer flea markets because you can sale it all in one day, make your profit and even leave behind stuff you dont want.

also there is a site called freecycle, people just give away all kinds of stuff, furniture, kids toys, even pets and electronics. you can arrange them by zipcode, ppl just list there phone numbers or addressses and say come get it.
