This month, we focus on Mysteries and Foreign Language. Hardcover Mysteries (except those in the new section) are 50% off regular price. That makes them a mere 50cents apiece- how’s THAT for an inexpensive form of entertainment? Foreign Language items, both in our Foreign Language section or in the Children’s room, are 50% off for the month.
