Manufacturers’ coupons will have their value doubled at participating stores only if they meet the coupon policy requirements of the store. For example, a coupon worth 50¢off one (1) box of cereal would actually give you $1.00 off at a store like Giant Eagle. Of course this only applies if the coupon itself does not specify ‘not subject to doubling’ or something similar. Many of the coupons you see on store displays will state this phrase, meaning they will only give you the face value of the coupon. Giant Eagle (according to their current policy) will not double internet printed coupons or coupons over 99¢. For example, a coupon worth $1.00 off one (1) box of cereal will not be doubled because it exceeds 99¢. You should always be familiar with coupon policies before expecting big results.
