Here’s where to buy The Expanse on Blu-ray before it leaves Amazon Prime

The Expanse is, by far, my favorite sci-fi series of the past decade. But unfortunately, select seasons of the series, which found a home on Prime Video after its cancellation on SyFy, will soon be unavailable to stream. According to their respective pages, the first three seasons of The Expanse will be leaving Prime Video on Feb. 6 at 4 p.m. PST.

Seasons 4-6 will still be available, but if you’d like to have the entirety of the series on hand to watch whenever you’d like, good news: you can currently pick up the Blu-ray box set featuring all six seasons from Amazon for just $62.95 (was $79.98).

Since the acclaimed series was never adapted to a 4K format, this 15-disc set is the best way to experience The Expanse, and it even includes commentaries and other bonus features you won’t find in the streaming version.

The Expanse depicts a brutal though fairly plausible near-future setting where the political powers of Earth, Mars, and the outer planets are in a constant struggle for resources and influence. In addition to its exemplary world-building, the series features a memorable cast of characters, awesome space battles, and a refreshing amount of (mostly) real science driving the action.

If you aren’t able to find the box set, individual seasons are also available to purchase piecemeal. Although they’re more expensive than the box set, we’ve detailed where you can find Blu-ray copies of each season below.
