This is the largest graphic novel I’ve seen at 99 cents and it’s high quality and timely as well with the tv series:
legionquest, the prequel to the original age of apocalypse 550 pages

It’s not marked anywhere and not included in the marked legion 70% off sale, which sells all ~20 of these issues for 99 cents each!!
Also there are a few more new release ones at 99 cents, thanos books, star wars vol 6, Star Wars a new hope, X-men grand design, etc mixed in at this link:

these may also be on sale at Amazon as well. Comixology no longer marks these as on sale with their own category and has hidden them away.
