Here's a promo code for Leap Frog. I read it in "Parent and Child" magazine. Not a great savings, but you don't have to purchase a large amount to get a discount.
Save $3 off a $10 purchase at http://www.leapfrog.com/
Enter Promo code: HY8FP
Valid until 1/31/09
(I'm not sure if that is before shipping and taxes or not)
