Amazon is running a new promotion where they’ll give you an extra $20 to spend on a new Kindle, on top of the regular trade in value, when you trade in your old Kindle. Amazon’s trade in program is always an option for getting money for your old gadgets, but a $20 bonus regardless of which Kindle you trade in is a nice bonus if you were thinking of upgrading. The $20 bonus can only be spent on a new Kindle, but the trade in value for your old one will be issued as an Amazon gift card which can be used on anything Amazon sells. The trade in value you receive depends on the Kindle model you have and ranges from $5 for broken devices, to $50 for newer models. Even if you trade in a broken Kindle for $5, you’ll still receive the $20 bonus.
