I used to own so many of them until my mom forced to give them to the poor.

Yeah, scare them into submission.

I ordered (eh.. my mother ordered..) the first 45 or so from Scholastic(sp?) book club.. while I was in grade school.

I used to own Welcome to Dead House all the way through How to Kill a Monster...so, almost the entire series. Then I got tired of reading them, and sold them at a garage sale to get some extra money.
