The digital world moves at light speed. Today's cutting-edge gadgets will be outdated tomorrow. It's why many people have a closet or drawer full of unused devices.
Throwing old gadgets away is dangerous because some contain harmful metals no one wants in landfills. Recycling or donating the gear takes care of that, but what if you want to make some cash?
You could make hundreds depending on the age and condition of the item. You just have to know where to look!
If you decide to sell on eBay, you have two options. You can set a hard price - the "buy it now" option - or put it up for auction.
Auctions can fetch more money, but only if demand is high. In most cases, I recommend offering a set price. Keep in mind that you should cover listing and shipping fees in the price of your device.
If you'd like to avoid these calculations, or have an item that costs too much to ship, you can stay on eBay with eBay Classifieds. Of course, there's also the standard-bearer for online classifieds, Craigslist.
