There’s a Michaels Coupon on their site for 15% Off your entire purchase, including sale items.
You can even have them send you the coupon via text to save on ink.
Coupon valid through 1/26/13.
I downloaded their App recently on my iPhone and received a 25% Off my entire purchase coupon via the app. May be something to check into if you are making a large purchase.
They have lots of Valentine’s things there that might come in handy if you are planning a school Valentine’s party and need crafty ideas/decorations.
