Well there's the kindle version here:
https://www.amazon.com/Finder-Deluxe-Secret-Vol-Manga-ebook/dp/B01N9WBINB/ref=tmm_kin_swatch_0?_encoding=UTF8&qid=1488325460&sr=8-1
But if you want pdf + reader on Sublime's website, you'll have to wait until they put up a page for it (usually they put it only a few days before the release).
You can buy the digital version directly from the SuBLime homepage, once it becomes available. You put the digital version in the shopping cart, proceed to checkout, pay for it and you will then instantly have access to it via two options which you will always be able to use: a) you can read it online on the SuBLime page (in your personal account, where your volumes will always be available) and 2) you can always download the volumes you bought on your personal harddrive as a PDF-file so you can read it offline any time you like.
SuBLime doesn't list the digital version for the Finder volumes just yet, but to give you an idea, here is the one for Crimson Spell, Vol. 1. The "digitial version add to cart" is on the right hand side.

So once the digital version of the finder volumes becomes available you can just search for it on the SuBLime side and order it that way.
