( CNN ) -- If you received shiny new gadgets for the holidays , you probably have some older device that is now unwanted or obsolete . If you ca n't regift your old computer , tablet or TV , make sure you get rid of it the smart way by selling , donating or recycling it . Before you part ways with your device , make sure to wipe it clean and permanently delete any personal data . Sell for cash . If you 'd like cash in exchange for your gently used gadgets , you can sell them online . How much money you earn depends largely on how much time and effort you 're willing to put into hawking the device . It 's easy to get caught up trying to get the best possible price for your old iPad or smartphone , and before you know it you 've wasted a chunk of your holiday vacation jockeying for an extra $ 50 . Selling directly on sites such as Craigslist , eBay or Amazon can net the best prices , but it also comes with its own set of hassles , including the time commitment required to sign up and create a listing , as well dealing with flaky buyers . Technology depreciates quickly , so you 're unlikely to make back the full $ 500 you spent on an iPad 2 just last year . To find out how much you can get , look at past eBay auctions for the same item . Do a search for the gadget name and select `` Completed Listings '' from the Show Only menu , then select the auction tab at the top of the list . Prices will vary according to condition . For example , an unopened Nexus 7 in the box recently went for $ 251 , while a Nexus 7 with a cracked screen sold for just $ 81 . You can also check Pricenomics.com to see a list of current sales and a handy chart showing the average price of the device over time .

If you 're going to use any profits to buy even more technology , trade-ins can offer a better deal than selling .
