I don't think we have any preschool teachers, do we?
Teachers of youngsters - check this out, Scholastic $1 ebook deals!
ETA: For the rest of us, if you go to Parent Resources here, there are a bunch of $1 ebooks that are "easy readers" - quick little stories, might be useful to keep on your phone/tablet/ipod for a quick distraction?
Re: Preschool/Elem teachers, $1 books!
Can't beat that!
