If you have been wanting to upgrade your Kindle, now is a great time. You can get a $20 instant credit plus if you trade an your old e-Reader you will get an additional gift card.
This discount is eligible for the Kindle, Kindle Paperwhite or Kindle Paperwhite 3G. The $20 discount is instant. For example, the $20 discount would drop the Kindle 6″ with Wi-Fi to $49 from $69 with special offers.

Plus you can trade in your old e-Reader and get a gift card for that. The amount depends on what you are trading in and the condition. You can head over here to see all the brands accepted.

I was really excited to do this until I got to checkout and realized you have to sign up for the Amazon credit card to get the $20 off – NO THANKS!
