I’ve never seen those Joann calendars. Definitely going to look for one. I've had good luck using coupons that Joaanns sends through the mail. On several ocasions, my local Joanns has applied two different coupons to my purchase, one for percent amount off a single item (they took percent off highest priced item) and then also used the percent off your entire purchase including sale items one and so I got the most expensive item discounted twice.
