Rite Aid: If you have a coupon for money off your entire offer, present that to the cashier first, then hand over any other store and manufacturers’ coupons for specific items.
CVS: Scan your ExtraCare card first to ensure you get Extra Bucks. Give money-off coupons next (such as $3 off a $20 purchase), then other store coupons, manufacturers’ coupons and, lastly, Extra Bucks.
Walgreens: Even diehard clippers do not agree on the best order to hand over coupons at Walgreens. Your best bet is to try different combinations until you find the one that works at your store.
