Last time I had a 40% off and another 20% off entire order they wouldn't let me use both. It had to use one or the other. Can you use both on the same order?
I think it depends on who is working the cash register at the time. They always let me use all my coupons at once whether from Michael's or ACMoore plus all of the different Jo-Ann coupons. Michael's used to but now have gone to only one coupon per trip. I tell them at Michael's that I teach crochet classes and used to send my students to them, but don't anymore because of that new policy. I think the most confusing coupon at JoAnn's is the extra 10-20% off coupons. Those can only be used on one item, not your whole order which you can only find out by reading the fine print or finding out when you check out. They can be used on an either regular or sale item. I think they are kind of misleading in their wording.
