Can you use sanctioned content as soon as you get the PDF?

[Sobak "Future Snake, Elf-Bane"]

I just got my AP book 3 PDF (subscriber). Looking through the RPGG, I meet all requirements to purchase a new toy out of it since I have a valid PDF and it is sanctioned, but one could make the argument that the street date is still 7 days away. Is this argument substantiated anywhere or just a personal opinion?

This question may be fueled by a burning desire to use

Spoiler:

Book/PDF, check. Item allowed by additional resources, yes.

I see no reason why you are not able to use the item even though the book in not available to everyone as of yet. An advantagee to being a subscriber.

Add me to the list of people who would love it if Paizo gave Pathfinder this kind of additional resources love.
