I've also found one 50% off Halloween coupon for Joann Fabrics:
http://www.joann.com/static/coupon/0.../halloween.gif (hope it works). The coupon code for online use is FXA305. Let me know if someone uses it and works.
What's the adress of their app where you get the coupons? I am really curios too! Thanks!
