[Question / Support] paperback in stock/out of stock

If a paperback version is "out of stock", does that mean these will ever be back in stock?
†¢ If yes, why not make them available for "pre-order" until they are back in stock again?
†¢ And if no, why not deactivate the paperback version all along as soon as it is out of stock?

Books do get reprinted, but there's no set timeline for when that reprint happens, which is why neither of these are really an option.

Thanks for the answer.

I found the following page Reprint Status of Titles
The last update of this page was 2 years ago... :-(

e.g. [Anthology] Monster Girls With a Need for Seed (going to print in January 2023)
1. Are these already reprinted?
2. How come they are already out of stock?

Others say "ETA: Late February 2023" and others say "ETA: Mid May 2023"...

Now I really do not know whether these reprints already happened and they are already sold out (good for you!) or if there was no reprint so far.

3. Is there a way to purchase books and get them shipped as soon as they are available again?

The post was two years ago but it's actively updated, as evident by the 2023 ETAs. The turnaround time for reprints is several months, so anything still out of stock wouldn't have arrived yet. Print runs are planned in such a way that they shouldn't instantly sell out as soon as they arrive, so there's usually no rush in getting them right away. Currently there's no pre-order system in place for reprints.
