- "Family Library lets you link your Amazon account to that of another adult in your household so you can easily share Kindle books, apps and games, audiobooks, and Prime Instant Video streaming
across your Amazon devices and Kindle reading apps." Also includes 2-day shipping.
Go to https://www.amazon.com/mn/dcw/myx...gs/payment
and invite an adult to join your household. If one of you has Amazon Prime, then both adults will get the benefits. You can only invite one adult, and you have to be willing to share payment information
(basically proof that you're in the same household).
