Samsung has been teaming up with Marvel to promote the new Avengers: Age of Ultron movie, and the newest promotion offers a free limited edition set of 4 Avenger themed cases with the purchase of a Samsung Galaxy Note 4.
Samsung says these cases are valued at $200 (which sounds a little exaggerated), but its still a cool companion for the Avengers fans. The offer is valid only valid for U.S. customers, and there are only 4300 sets to give away, so time is of the essence. Once you have purchased your new Galaxy Note 4, you can claim your free Avengers cases by following the source link below.
In the past, we have seen Samsung and Marvel team up for a two-part video promotion for the Samsung Galaxy S6 and the new Avengers movie. Earlier this week, Lee Young-hee, head of marketing for Samsung Mobile, said that Avengers versions of the Galaxy S6 and Samsung Galaxy S6 edge are on the way.
