Purchase must be made today or tomorrow and total at least $5 before tax. Coupon says not valid on clearance items. YMMV on that as I know BB&B 20% coupons will take off even on those things they expressly say they exclude (part of the customer appreciation thing). Don't know how strict Michael's is on enforcing their terms. If nothing else, good for materials (glue, etc).
