Sadly, two good sales occurred recently. From Llewellyn, I got the Mibramag Magical Tarot and the Golden Dawn Enochian Skrying Tarot at deep discounts. I know the latter isn't really tarot, but found the description of it intriguing. The other looks like a fun, quirkky deck which seems to be developing into a sub-collection for me.
New Age Discount Books had a $5.00 sale on some decks I'd been looking at while they were twice that price or more-Yoga Tarot (supposedly the set with bag), Contemplative Tarot, KamaSutra (also the set), and an oracle deck. So I'm done buying for awhile - except on Amazon where I have gift cards to purchase with.
