Just when you thought it was safe to put away your wallet, Amazon has declared Friday, December 30, Digital Day: 24 hours dedicated to buying movies, music, games, and other digital content for the device you may have just received for the holidays. Amazon will offer substantial discounts on digital downloads: up to 80 percent on games like Battlefield 1 and Rocket League and as much as 50 percent on movies and TV shows, including The Martian and "Supergirl."

The all-day event starts at 12 midnight Pacific Standard Time.

Sign up with Amazon to hear about deals as they happen.
