From comments on Minna's latest blog post:

The actual printing is being crowdfunded ... so the first ~1,000 books go to the folks who have participated in that campaign. Another ~1,000 books will be produced on top of that to be sold "normally" - historically either through Minnas own webshop, or HiveWorks' - in batches.
No date has been announced yet, though, and batches tend to sell fast these days. Keep your eyes peeled and pointed at this website to learn about upcoming sales in time ...

This is correct. The sale of the extra copies will most likely begin sometime after summer, and I'll probably be selling them in much larger batches through Hiveworks this time.

... I missed the kickstarter for book 1 of SSSS and i'm infinitely sad - will there be another opportunity to buy it? I would love this book so bad and am willing to pay all the monies if necessary haha

Yup, I've got a price quote from the printers and I'll be able to print up ~1,000 extra copies with the additional money that the print drive made, I'll start selling those after all backer rewards are sent out. Possibly either late summer or early autumn. (And I'll be saving the profits of those books to print more if and when they eventually run out.)
