Level Up (A5E) Best place to purchase the 5e/Level Up Zeitgeist Adventure Path?

[Libertad]

Don't know if this is the best place to ask, but I've been meaning to get the 5e version of Zeitgeist for a while. I'm aware that the adventures are available as their own separate products on EN Publishing's storefront, but together they're a tad pricey. I have heard that you can get the adventures on EN World if you're a Patreon subscriber. On Drive-Thru RPG only the main setting book, Adventures in Zeitgeist, is available and not the 5e-ified adventures.

I'd like to know what purchasable options are out there to make the best decision for my wallet.
