You’ll find a $1 coupon for this cereal in the latest issue of All You(orange cover) on page 12. Can you use a coupon on a mail-in rebate item? In this case, you bet! Manufacturer’s who issue rebates are fully aware of what coupons they have also issued for that product. But they expect few consumers to match-up the coupon plus the rebate together, and allow those who do some extra savings. Other rebates will automatically subtract the value of the coupon form the rebate amount (whether you used the coupon or not). So go ahead, use that $1 coupon and get your full mail-in rebate!
