I love Costco, and not only because I might be one of the few people for whom it actually makes sense to buy cans of olives in eight-packs. A new reason has come to my attention, which is that you can now trade your old electronics in for Costco cash cards, and be eco-friendly, to boot!

The program is powered by Gazelle, and is pretty simple. You go online, you tell them what you have to recycle, they tell you how much they’ll pay for it, and then they send you a box to ship it in, free of charge. So what is this Gazelle, exactly?

Gazelle is the nation’s largest reCommerce company, providing a practical, responsible, rewarding way for consumers to get value for used electronics. Today, we accept products across a wide range of categories and have found a new home for more than 20,000 used electronics, while responsibly recycling thousands more.

We are creating a revolution in consumption, inviting everyone to think differently about the products we buy, own, sell, and dispose of. Our vision for the future is that every consumer electronic is considered for reCommerce and that none ends up in a landfill.

I did a couple trial runs on items to see what you can get for them, and though the money isn’t insane, it’s a great way to recycle your electronics safely, and get some Costco cash in the exchange. And don’t worry about any private data–they wipe all your stuff clean before they do whatever they do with it.
