I haven't ordered online myself. I have a friend that orders from them and gets the discount off the total yardage of a fabric. In the store, I've heard them discuss panels and coupons (1 panel per coupon), but not fabric. I've always gotten the discount on the total yardage of a fabric. But then again, what you get sometimes depends on the clerk. I've had some that let me use multiple coupons and some that won't.
