Do you have any electronic devices or smartphones lying around? Here are some ways to sell your old electronics for top dollar.

Get the best deal when selling old gadgets

The Financial Times of London estimates there’s about $5 billion in unwanted phones sitting in people’s drawers. Don’t let those unloved phones gather dust! In addition to old standbys like Craigslist and eBay, you can try these sites when you want to sell used electronics:

• Swappa.com for Apple & Android devices
• Glyde.com for Apple & Android devices plus video games
• Gazelle.com for Apple products, plus Android, BlackBerry and other phones
• Gizmogul.com lets you sell old phones for cash and donate to charity at the same time
• BuyBackWorld.com for all electronics
• NextWorth.com for phones, cameras, tablets and games

Meanwhile, Amazon, Walmart, Best Buy, GameStop and Apple have their own trade-in programs. Though in general, you’ll get a better deal from the independent players listed above. But you’ll usually get the most money by selling your phone yourself on eBay.

Also, older cell phones can always be donated to soldiers through AnySoldier.com or to domestic violence shelters through ShelterAlliance.net.

But those aren’t the only options. Coinstar has a kiosk called ecoATM.com that uses artificial intelligence and extreme digital photography to determine a value for any gadget you want to sell to the machine.

The ecoATM will fingerprint you and make a photocopy of your picture ID before they make an offer. You get cash or cash equivalent on the spot if you accept their offer. But for 30 days, the company holds onto the phone. If it turns out to be stolen, they turn over your image to the police. It’s all part of an effort to try to prevent ecoATM from turning into just a high-tech fencing operation.

If you’ve got some gadget like a very old TV that has no value, try FreeCycle.org to help move it along to somebody who might be able to use it.
