One more month for ShillerMath deal

Just wanted to remind you all that ShillerMath has offered you an extra $100 off either Kit 1 or Kit 2 if you order before the end of June and use the special code available only here:

KatPat11.

That's an AMAZING deal -- less than $100 a year for a kit that lasts all your children.  Snap it while you can!
