The First Alert FAQs

How do I use my First Alert coupons?

Can I Use Multiple First Alert Coupon Codes at Once?

First Alert does not permit the use of multiple coupon codes simultaneously, a practice known as 'coupon stacking.' Since only one discount code can be redeemed per transaction, we suggest finding the best First Alert offer available. Usually, that promo code will apply to sale items, allowing you to maximize your savings even with a single First Alert coupon code.

Why didn't my coupon code work?

Your coupon code might not work for several reasons: - It may not apply to the items in your cart. - It may only be valid for first-time purchases. - It may have expired.
