As a parent you can subscribe to Epic (an online digital library for children ages 12 and under) for three months for $3 total...that is an insanely great price for access to a ton of digital books for children over the summer.
There are a lot of great resources within Epic from ebooks, audiobooks, videos, and read-to-me stories.
You can cancel after the three months (but don't forget to do that or you will be charged the normal monthly fee - $8 I believe).
Classroom teachers can sign up for a free account but that is limited to use in the classroom only (not at home).
If you are interested you have to sign up by June 12th to get the deal.
