Carly Fauth surfs the web and calls it spring cleaning.

“I purge clothes, electronics, anything we’re not using,” the mother explained.

These days, new websites allow you to turn your trash into cash.

“A ton of different sites have popped up, to help consumers not only get rid of their unwanted stuff but help you make a little bit extra cash,” said Kyle Taylor with ThePennyHoarder.com.

Unlike CraigsList, or ebay where you have to find a buyer for your stuff, many of these sites act like a middleman, paying you up front first and selling your goods later.

“So it makes it really easy because you get a cash offer right away,” said Taylor.

Got a closet full of clothes your kids have outgrown? ThredUp will take it off your hands, and hand you cash in return.

“We send you the bag, you stuff the bag with all your outgoing stuff and you simply put it on your door and we come and pick it up,” explained James Reinhart, CEO of ThredUp.com.

Maybe you are ready to redecorate.  Chairish.com acts as a virtual showroom for your used furniture.  Once it sells, they send shippers to your door to take it away.

"If you’re fearful of dealing with somebody on Craigslist, this cuts out that process,” said Taylor.

There's also UsedInstrumentBuyer.com.  Once your child's old sax plays its swan song.

“They’re re-selling instruments all over the world and so they’re going to be buying a much greater variety,” said Taylor.

If you have electronics to sell, you might try Eco ATM, an actual kiosk that will take your old electronics on the spot and give you instant cash.

“I put the phone in and they quoted me $146, which was pretty good,” said Fauth.

Of course, with the convenience, there is a cost, with each site taking a cut.

“You’re paying a lot more in commissions than you would with a site like Craigslist,” added Taylor.

But Fauth says for her, it's worth paying a little extra to get it all off her hands.

“Just finding a way to get rid of stuff and make money at the same time, it’s just…to me it’s a great feeling,” said Fauth.

Experts say the payout you get from these sites can vary widely and consumers should shop around for he best offers for their goods.  And while commissions may be higher than just selling directly on CraigsList or ebay, they tend to be less than some brick and mortar consignment shops.
