Teacher Appreciation Week....cont'd

I keep forgetting it's Teacher Appreciation Week. Youngest Princess and I walked into school this morning and there was a mom there giving Youngest's teacher a floor puzzle. This mom's daughter had been in Mrs. N's class a previous year. Boy did I feel like a heel. I told Mrs. N that I just keep forgetting it's TAW, but we really do appreciate you!!

So any suggestions on what I should get? I thought maybe a gift certificate to a teacher supply place we have here. I'm just not sure she goes there. It's spendy! I may go take a look around though and see if I can find the perfect thing.
