I just found a company similar to House Party but it is a Facebook application.  It is called Hosties and currently they are taking applications for a Juicy Juice party.  Click Here to apply though their Facebook page.  If you are selected to host a party for your kids you will receive:

*4 free Juicy Juice Sparkling Fruit Juice Beverage

*10 $1 off coupons and fun gifts for you and your guests
