Right now if you shop directly at the Fisher-Price Store, you can ship every order for free with coupon code FREESHIP. Check out the Sale section for five pages of bargains!
I’m seeing lots of deals on Imaginext items, so this is a particularly good one to check out if your kids are into that. Personally, I’d get the Evil Dr. Porkchop Flashlight as a stocking stuffer if my kids were smaller. (Oh, who am I kidding? I might get it for one of them, anyway.)
[Edited to add: Oh, dear. I've worked my way to the end of the Sale section, and they also have $5 Sing-a-ma-jigs. Those things give me nightmares.]
