If eBooks have taken the place of MMPB in terms of price, why is it that Star Trek eBooks are priced at TPB prices (other then those on sale)?
You keep ignoring the point that these are two different subjects. One is a larger industry trend that has nothing to do with
Star Trek books. The other is how Pocket/Gallery has chosen to react to that larger trend with regard to ST books. As I said, they
could have gone to e-books only, but instead they chose to reorient the publishing line toward trades. Remember, there have been
Star Trek trade paperbacks for a long time, just mostly anthologies and omnibus volumes. So the Trek TPB line was already around
alongside the MMPB line. So with MMPBs gone, that leaves the existing TPB model, which they chose to retain as the new home for original novels.
As for the price issue, you'd have to ask someone more aware of the business details. But I assume it has to do with what people said above, that the difference in production cost between print and electronic books is minimal. The reasons for setting TPB prices higher than MMPB prices would apply just as much to the e-book releases of books that were created to be TPBs. Trades are generally longer, bigger books. They're more prominently marketed, more of a prestige item. There are fewer of them per year. I'd assume that all factors in to determining their market value.
The question that needs to be asked is how are sales at the higher price then sales at $7.99? Only S&S have the answer.
Again, though, it's not a one-to-one comparison. MMPBs are on the shelves for a short time before having to be sent back, while TPBs stick around longer and thus can build sales more gradually. Also, once again, there are fewer of them per year. If they cost, say, 1.5 times as much but come out only 2/3 as often, then that cancels out and the cost for a year's worth of them is the same.
How come the eBook that takes the very same work to make previously was $7.99 when Star Trek was mostly MMPB and now that it's trade, why is the price $11.99 for the same eBook formats and for the same work?
I don't think it is the same, not on the production or business end. The reason customers have to pay for products is to pay the salaries of all the people involved in creating them. Those salaries are based on their work for the company overall, and Trek books are just one tiny, tiny part of what Gallery (aka Pocket) Books publishes. So the prices that are set for TPB publishing would be about what TPBs are worth on the market overall. Again, there have been Trek TPBs for a long time, and they've always been more expensive than MMPBs.
Yes eBooks are replacing MMPB sort of. But not at the MMPB price point. eBooks are being charged at the price point for HC or TPB. So that really doesn't make them a MMPB replacement.
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.
