What does an "ad-supported" Kindle mean?
Amazon refers to certain Kindle models as "Ad-Supported." These Kindles will display personalized ads on the lockscreen when it is in sleep mode. You'll save $20 for buying an ad-supported Kindle. You can make a one-time payment to remove the ads, if you choose to do so later down the road. If you want to purchase a Kindle without ads, look for "Without Lockscreen Ads."
