If you plan on upgrading your e-book reader, look no further than Amazon as the online retailer has extended its Trade-In program to allow people to trade-in their old Kindles and other e-readers. Trading in such devices is valued anywhere between $18 and $135 depending on the model and condition of the e-book reader.

After having your old e-reader appraised and traded, Amazon will send you a gift card corresponding to the value of your device, which you can use in Amazon.com to purchase other items, or even hold on to it until the retailer releases the Kindle Touch and Kindle Fire. Do not worry about additional costs as Amazon also offers free shipping.

Visit the Amazon Trade-In program page for more information. The process itself takes only a couple of minutes, even shorter if you are already registed on Amazon.
