Again, you're confusing Trek books with the entire industry. If you look outside of Trek, e-books are generally priced lower than trades. For instance, the e-book edition of my original novel Only Superhuman is priced at $7.99, the price of its MMPB release, even though it was barely out in MMPB for a few months before they remaindered them all. And you can find plenty of other novels at discounted prices on Kindle or Nook or whatever. For instance, the first book in The Expanse series is currently on Kindle for $9.99 marked down from the print list price of $17, and you can find other novels for 2-3 bucks. If Gallery/S&S won't discount Trek e-books, that's specific to them, and it's a separate issue from the industry-wide reasons why MMPBs are a dying format.
