Best way to pre-order Pathfinder 2E to get rules before Gen Con

[Cyrad]

Having registered for 2e events at Gen Con, I want to ensure I get the rule set as soon as possible before the event. What method of pre-ordering or subscribing should I do? I don't mind getting a PDF.

I ask this because I had pre-ordered Starfinder's Core Rulebook for Gen Con 2017 only to discover I couldn't pick it up at the event and it would not arrive before the event. So Customer Service had to change my order to a subscription so I could get a PDF. I want to avoid this situation happening again.

Sign up as a volunteer to GM 2E at Gen Con and you will get access to a slightly modified PDF copy of the Core Rulebook a few weeks in advance.
