Here's what I found that she liked and met my requirements:
It takes you to the main screen, which has an option to buy. However, everything I clicked around on in the games worked fine. Start here, if it doesn't work from the main screen.
There are some printable resources as well.
[EDITED TO ADD - It appears that only the first 3 levels are free. If we work through those levels and they are effective, we'll probably buy the program if I haven't found anything better. I really like it and Suzy liked doing it. More than that though, it seems like it will really help.
EDITED AGAIN - A friend found a promotional code WSBJ which should bring the price down to $20 a year. I haven't tried it yet.]
