Compared to the days I used to pay for DVDs and Blu-ray Discs these are great value to own, especially if they came with bonus content (aka iTunes Extras). But in the era of video on demand, the low level OCD in me where it’s own one, gotta own the whole series/franchise, it could still get mighty expensive, with nothing to show for it on the bookshelf…
For all you young kids out there, I paid around $170 for season boxsets of The X-Files, and that was “cheap”, a couple of decades ago.
