Earlier this week, we heard that Samsung is prepping a special “Iron Man” edition Galaxy S6 that could launch as soon as this month. Turns out that that’s not the only Avengers promo that Samsung’s got planned though, as a new one for the Note 4 has been discovered.

Samsung has announced that anyone that buys a Galaxy Note 4 between May 4 and June 1 will get four free Avengers cases for their new smartphone. The cases include designs for The Hulk, Thor, Captain America, and Iron Man. In order to get your free cases, you just need to get your Note 4 during the promo period and then submit your receipt on Samsung’s website. Only 4,300 case bundles will be given out, though, so it’d be wise for you to submit your receipt as quickly as possible.

While we won’t know the quality of these cases until they actually begin shipping to consumers and appearing on Note 4s, they look like they’ve got some nice designs that I’m sure a lot of Avengers fans will like. And hey, it’s tough to complain about getting four free cases for your new phone.
