There's a money-saving promotion going on right now for anyone who pre-orders the Best Buy-exclusive Steelbook version of either Black Panther on Blu-ray ($28) or Black Panther on 4K Ultra HD Blu-ray ($35). Lock in your pre-order, and you'll receive a free two-month subscription to Marvel Unlimited. That saves you a cool $20.
A Marvel Unlimited subscription grants you access to over 20,000 digital Marvel comics you can read on your phone, tablet, or computer. It contains many of the most famous stories from the Marvel universe, including Civil War, Age of Ultron, and The Infinity Gauntlet, the latter of which was the loose basis for Avengers: Infinity War. It also contains curated reading lists centered around many of the most famous superheroes you've seen in the cineplex these past 10 years.

When you consider the $20 value of the two-month Marvel Unlimited subscription, that cuts away considerably from the cost of the Steelbook Black Panther movie, whichever version you choose.
From GameSpot's Black Panther review, "Black Panther is a top tier Marvel movie with all the humor, style, action, passion, and fun that the MCU has come to embody. Black Panther is a cultural event that's going to be hard for Marvel to top, no matter how many worlds Thanos conquers later this year in Infinity War."
