They are offering an additional 30% off their clearance prices section. Just be sure to shop under the Teacher's tab instead of the Parent section. They have much more available. I found some stuff I could put under the tree this December.

Also, flat shipping rate of $5.95 for orders of $75 or more. Promo code: FS108P

Didax also had some fun stuff in their bargain basement section. They also offer free shipping on orders over $65. Got a few neat workbooks for $1 and some fun games for cheap.
