Good morning,
Just a few words to add, since JoAnn has come out with the App for your smart phone they are not offering many coupons online that you can print they mostly offer the online ones for use on their store site. If you are not receiving your mail flyers you have to get the barcode scanned at the store this will keep you in the system and you will continue to get the mail flyers. Also if you have a magazine subscription to ASQ or any other quilting society you get the JoAnn 10% discount card.
Also, you can use as many coupons as you like as AZ Jane said they can not be the same coupon numbers. I used 5 coupons just yesterday, but the the only one that did not work was the 15% off entire purchase; but all the others worked for me.
