EDIT: Well crap.
If your child is a fan of reading, then 1) good job! and 2) you can get them a free copy of Junie B. Jones and the Stupid Smelly Bus by joining their Kids' Reading Club. This is one of those “while supplies last” kind of deals, so there's no telling if they have any books left or not.
