House party is notorious for not sending the emails to let you know til after it is filled. The secret to getting in to them is to check your email the evening before they say the emails will go out. They usually send them then, or at least that has been my experience. I have been picked for quite a few parties... Kids Bop, The Closer, Scholastic, XBox, Sargentos and now Wizards. All the packs have been great and our parties have been a blast.
