Just in time for the NCAA March Madness tournament, CBS now has a promo code for consumers to use in order to get a free month of their CBS All Acess streaming service.

The service has on-demand content from shows on CBS, such as The Big Bang Theory, Young Sheldon and NCIS. CBS All Access also has its own original shows such as Star Trek Discovery and The Good Fight, which was just featured in Apple’s Apple TV app email last week.

Additionally, users will be able to stream their live CBS network with CBS All Access. However, not all CBS affiliates are on the service, so it is best to check on CBS’s website to make sure that your local CBS station is available on the streaming service.

To get a free month of the service, you must type in the code “MARCHMAD” in the promo code box when signing up for the service. After applying it, it should take the cost of the service and transaction for that one month. This can be applied to both the free tier of the service and ad-free version. It also works for both new and existing members of the service.

You have between now and March 22, 2019, to redeem this offer. I’d also recommend that you put a reminder in your iPhone to cancel the service either after the NCAA Men’s Basketball Tournament (March Madness) is over or a day or two before they charge you for one month of service.

CBS All Access is on the CBS app, which is available on the iPhone, iPod Touch, iPad, Apple TV and Mac (on CBS’s website). To sign up for CBS All Access to use this promotion, click here.
