To reiterate, Disney and Marvel have not announced when Avengers: Endgame’s home release will be, but going off the typical release date pattern for movies nowadays, I suspect it will be available digitally in mid-to-late July, and the Blu-ray/DVD copies will follow in August. So if you’d rather not buy a copy of Endgame, but do plan on subscribing to Disney+, it’ll be another four-five month-long wait to watch it on there.
