Why trade in through Amazon? For one, the company accepts a wider range of items than others, and your payment can show up instantly as a credit in your Amazon account. As long as you'll spend that credit, it can be a good way to clean off your shelves and make a few bucks. Amazon tends to pay average - but not amazing - prices for trade-in items. You're essentially exchanging cost for convenience. It's always worth shopping around to see who will give you the best price, but Amazon's simple process gives it the advantage.
