While the new wording on the coupon should be clear enough for even the most uninformed cashier to interrupt, you can print the MB q(s) directly from their site and take the whole sheet of paper in to help make it even more clearer; this message prints at the top of the page:
PLEASE NOTE: If your coupons are being cut by a page break, please return to the Specials tab, locate the coupon that is being cut, click on it and select Print from the top of MealBox. This will allow you to print a single coupon and avoid it being interrupted by a page break. Meijer MealBox coupons can be combined with Manufacturer coupons. Only one Meijer MealBox and one Manufacturer coupon per item.
