Price Drop on Bluebeard Tales From Around the World

Bluebeard Tales From Around the World (Surlalune Fairy Tale Series) has dropped in price on Amazon to $31.57 with a 21% discount on list price. The last time it dropped it didn't last for long and went back to list price rather quickly and stayed there for months. I don't claim to understand Amazon's pricing algorithms but I'm happy one of my favorites in the SurLaLune series is discounted.
