All of the Call of Cthulhu stuff I've been fortunate to get my hands on across the years, but ESPECIALLY the Pagan Publishing stuff--Delta Green, Walker in the Wastes, Realm of Shadow, Mortal Coils, and the like. Pagan does top notch stuff.
Dungeon Magazine. I paid $10 for Whispers of the Vampire's Blade (a single adventure), but $7 for Dungeon __(insert number here)__ which usually contains 3 adventures. You do the math.
Greenwood's Volo's Guide to ________ series. The first was Waterdeep, and it revolutionized the way I thought about D&D and what could be done with it.
Dark Sun & Planescape, the campaign settings. I have every product from both of those settings and cherish them.
