Since a few people asked how to get access to the teacher store, I thought I'd just put it here.  So sorry it's taken so long, we had a long Christmas break since we work through the summer and I hadn't been here at the hs blogger site for awhile.

When you go www.Scholastic.com, you'll see a space to sign in and register,after clicking on that, you'll see where you can choose to register as an educator or parent.   Click educator and it should take you through a process for signing up.  I can't remember the exact details but recall that it had you type in your school name and then the computer does a search in your area, being a homeschooler, it won't show up, and you'll get a message that a representative will call you.  They ask for your school district so they can verify you as a homeshcooler, but here in Texas we don't have to register with anyone at all, and so Scholastic just took my word for it.   It took me signing up two times and about a month before I got a response, you might get a faster response by calling them. 

Once you're approved, you can sign up to receive notifications of warehouse sales in your area and they'll send you the book club catalogs.

Hope that helps someone!  Oh, and also be sure and take advantage of the educator discounts at Barnes and Noble, Borders, and Half Price books.  It's not possible to have too many books!  ;)
