How Can I Buy the whole Alice collection?

I loved the Alice series when I was in middle school and high, and would love to buy the whole collection for my niece.  I understand that the books come in three paperback collections:  Alice in grade school, Alice in middle school, and Alice in high.  Where will I find them listed on this website?

Here’s what  you do:   On the opening page of my website, in the red bar at the top, click on “Alice Series.”   You’ll land on the “Alice” page.  Scroll down to the words “Books in order.”   The last three books shown are the three boxed sets:  Alice in Elementary;  The Middle School Days; High School and Beyond.  If you click on any one of them, you will see the titles of all the books in that collection.  If you buy all three collections (and my website lists the places that sell them) you will have all 28 books, from “Starting with Alice” to “Now I’ll Tell You Everything.”
