Am I still blogging about Harry Potter, after all this time? Always. But seriously, I will always write a Harry Potter deal if I see one! Today’s HP Deal of the Day is the LEGO Harry Potter and the Prisoner of Azkaban Expecto Patronum, which is $16 on Amazon. The 121-piece building kit includes a minifigure of Harry Potter, Sirius Black, two dementors, and Harry’s stag Patronus.
