Scribd subscription, 3 months for $25, 6 months for $50, or 1 year for $100
Kindle Unlimited subscription,$9.99 a month
If the bookworm you're shopping for is all-in on ebooks and doesn't own or want a Kindle, get them a Scribd subscription. For less than $10 a month, they'll have access to hundreds of thousands of ebooks, audiobooks, magazines, and newspapers. Your giftee can read and listen to Scribd books on the apps for Android, iOS, Fire Tablet, or on the Scribd webpage. Ebooks and audiobooks are downloadable for offline reading. To learn more about Scribd, read our full review of the service on Insider Picks.
It's important to note that you cannot get Scribd ebooks on a Kindle, so if your giftee has or wants a Kindle, get them signed up for Kindle Unlimited, which is a similar service for Amazon's Kindle ebook reader and its Kindle apps for iOS, Android, and the Fire Tablet.
