Powerbooks has some selections from different publishers. Fully Booked usually stocks Lo Scarabeo titles (though sadly, not all), and some other publishers - they have the most variety i think. National Bookstore used to have the Osho-Zen and some other titles, but i think they've transferred most of their tarot selections to powerbooks - though in some branches, they still have some Fournier decks. there's this small voodoo-themed resto in Katipunan called Gayuma which used to sell some harder-to-find titles here such as the Phantasmagoric. I don't know if they still have the decks there, though, as it's been a while since i last went there. And i've seen a couple of used decks pop up every now and then on Ebay Philippines. hope that helped.
