Do you have an older Kindle device or one that you would like to trade in for a newer model? Amazon has a pretty nice trade in promotion right now.
You can mail in your old Kindle and they offer a credit based upon the specific device plus a bonus $20 credit to use toward purchasing a new Kindle.
The trade in value isn’t huge- up to $35- but considering mine is probably 5 years old and I paid about $100 for it. Not too bad of a return. Plus the new devices are so much less expensive than they used to be.
I haven’t seen this promotion before and I am not sure how long it will last. Please note Amazon can change pricing or promotions at any moment. All information is valid as of 9am PST 3/2/17.
