The app allows you to browse and watch movies instantly (if not sooner), reserve copies of hit titles at your local Redbox kiosk, and also allows you to rent or buy videos digitally. In addition, the app will also show you a map to direct you to the closest Redbox kiosk near you. An $8 a month charge includes unlimited streaming for the month and 4 DVD rentals a month from the kiosk, which can be upgraded to Blu-ray for $1 more.
The first month is a free trial period which allows you to stream unlimited movies over your handset, plus pick up 4 DVDs from a Redbox kiosk.
