Query: Laugh Again

Dear Sirs;I purchased several "books" of Laugh Again earlier this year. When I ordered three more of what appeared to be the book, I was sent three study guides. I was very disappointed as I needed the books for a group that started already. Those who the books were ordered for had to go find their own and pay full price. Please make sure that study guides are labeled as such. Perhaps it was and i made the mistake.
