Are you allowed to buy stuff from the U.S. or Canada on eBay? There's a ton of Dragonlance books available (I've got that as one of the searches that get sent to me in my daily email because there are some I'm still looking for). I know the Defenders of Magic books are listed, because I bought two of them to replace my original copies that got damaged.
The Leaves From the Inn of the Last Home books are interesting, too. They're source books, but also have recipes (which really work; the SF club I was part of in college tried them out for one of our parties), and sheet music for the songs. I learned
Est Sularus (the hymn the Knights of Solamnia sing) and it's just gorgeous. I cranked up the volume on the organ and let it soar.
