Cheap Way to Store Lego Books

I love Staples.  For real.  I bank rewards like no tomorrow.  I also think they also have some killer deals from time to time and I like to hoard office supplies for some reason.

Over the summer, I got a big thing of sheet protectors for $5 (normally $14.99) and I recently used my Staples Rewards to pick up some binders for free.  I had a mission and I finally "did it".

These were all of our Lego books that have been lying around and all different places. 

Here are our Lego books all nice and neat - in page protectors and fill up 2 3" binders.

 Now, if I can just find a good way to organize the actual Legos, we'll be all set.
