Well, I've discovered that there have been several additions to the series and updates (second editions to many modules) as well--the deal for e-Sword is 43 volumes; currently there are 54 volumes. This means this is lacking the most recent scholarship, which means it's a bit dated. That's not bad, but it explains the very low price. Logos and Olive Tree charge almost $1900.00.
At any rate, it is most certainly a good deal for what it is.
Greetings. Oddly the link you gave was still valid as of 4/19/2022, when I purchased this set using the link you provided. I checked it today (6/12/2022), and the discount still seems to be avialable. This set has 56 volumes, including some dated as recently as 2020! I'm pretty sure it contains the updated volumes. Here is a complete list of the set and what it included at the time I purchased it:
