The best cure for clutter is to avoid it. That’s why I always try to sell a gadget when I buy a new one to replace it. This way I don’t end up with drawers full of old cell phones and half-megapixel cameras. To this end, eBay and Craigslist are modern miracles you should certainly employ. But if they have any drawbacks, it’s that you have to spend time marketing your items nicely so they will sell well, and then you have to manage the transactions with the buyers.
Well, if you want to avoid these potential hassles, check out SecondRotation.com, a service brought to my attention by Leo Laporte on MacBreak Weekly. Basically you visit the site, search and find the gadget you want to sell, rate its condition (e.g. do you have the original manuals and cables, is it nicked or scratched), and it calculates a trade in value for the item. If you’re happy with the offer, you schedule a free package pick-up with DHL and send it to them. They inspect it and if everything is as you described it, they mail you a check or credit your PayPal account. That’s it. Nothing else to do.
You’ll probably get less money for your gadget this way than you would buy selling it yourself, but the difference is convenience. What they do with your gadget is a mystery I couldn’t solve, but I imagine they sell them on eBay or a similar market. (If you have an idea, let us know.)
