I have a dear friend who has a website where she sells homeschool materials, inexpensive books and a wonderful organizer. The organizer is a ebook but the thing of it is that she is making new pages for it all the time. When someone who owns the organizer writes her and tells her that they need a page for something she will make it. Her price is great $5 and you can download all the pages she makes durring the year. I have all of her planners for the last couple years and I love them. The other books in her store are not more than $15 if that. She does have some books that she has used for her children that she is selling on her site and some of those may be a bit more but the books she created are no more than that.
