There are finally box art covers for The LEGO Batman Movie home media from various retailers. The retailers have some of the usual same items like the standard DVD, Blu-Ray combos, and 4K Ultra HD but there are also exclusives. It looks like Walmart has a couple of store exclusive versions including the Blu-Ray Combo which includes a lunchbag. They also have a Walmart version of the DVD as well as a Special Edition available as well.
As I mentioned before, Target also has an exclusive which includes the Batgirl (30612) minifigure polybag in which she is too is exclusive with a new head. The combo pack also includes some postcards as well.
The home media is now available for pre-order and it looks like the release date is June 13. Thanks to Bryan for the heads up.
