The M&M's FAQs

How do I use my M&M's coupons?

To apply the coupon, click the 'show code' button next to the code on this page, and paste it into the 'discount code or gift card' box at the checkout and click 'apply'.

How many coupon codes are currently available for M&M's?

At the moment, there are a total of 11 active coupon codes that can be used on the M&M's website.

Can I Use Multiple M&M's Coupon Codes at Once?

M&M's 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 M&M's offer available. Usually, that promo code will apply to sale items, allowing you to maximize your savings even with a single M&M's coupon code.

What payment options are available at M&M's?

M&M's accepts all major credit and debit cards, PayPal, and digital wallets.

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.
