Looking to get rid of an old computer, digital camera, or MP3 player? Sears just launched a new trade-in and recycling program that allows customers to exchange unwanted electronics for gift cards redeemable online or in stores.

Here’s how the program works:

Log onto sears.gazelle.com, where you’ll be prompted to enter brand and model information, indicate whether the device works or is damaged, and answer questions about condition and the presence of various accessories. In the case of personal products like MP3 players, you’ll also need to reveal whether the gadget has been monogrammed (which decreases the value).

Once you’ve provided the information, click ‘calculate,’ and up pops the trade-in value. A Nintendo Wii gaming console, for example, in perfect condition with all of its accessories, is worth $102. In poor shape, it’s worth just $20.

Other products eligible for trade-in include cell phones, PDAs, video games, movies on DVD, camcorders, GPS systems, Blu-Ray players, satellite radios, camera lenses, calculators, and home-audio gear.

In partnership with Gazelle, a dedicated gadget buy-buyback company, Sears offers free live chat support and pledges to wipe all items clean of personal data as part of its inspection process.

If you’re satisfied with the offer, the company will provide free shipping and packaging to return the equipment. You’ll get your Sears gift card in a week or so. Sears will also accept for recycling electronics items that no longer work. Recycled items, however, have no trade-in value.

As a special holiday promotion, Sears says participants will receive a 5 percent bonus over the actual trade-in value through Dec. 31.
