Found some great printable coupons here for JoAnn's. Scroll to the bottom and there is one for 20% off your entire purchase, including sales items. Just thought I would share with all my readers, since most of you are fellow etsians and cutting costs on supplies is top priority.
Also, just in case you did not know, you can use more than one coupon at a time. They may say only one per customer, but they are referring to only one of that specific coupon. If you have a 40% off one item, a 50% off one item, and a 20% off entire order, you can use them all. We saved about $40 the other day using 5 coupons.
