What to do with those outdated electronics? If you don’t want to sell them yourself on eBay or craig’s list, send your old working cell phones, MP3 players, laptops, GPS systems or other electronics to Gazelle. Evaluate the condition of your device online and they will give you an estimate. They will even pay for shipping by sending you a postage-free box. The entire process takes about a week after they receive the item. The company claims their average payment is $115.00, a great way to make some extra holiday cash.
