M&M's Promo Codes & Coupons September 2025

If your M&M's promo code says "invalid" or "not applicable to your order," it usually means the code doesn't meet the current order requirements or has expired. This is a common scenario, especially if the code is restricted to certain products, order minimums, or has already been used.

Typical error messages include "invalid code," "not applicable to your order," or "code expired." These often appear if:

• The code is only valid for select items or categories (e.g., "15% off select items" or "sitewide with $200 minimum order").
• Your order doesn't meet the minimum spend requirement.
• The code has expired or was entered incorrectly.
• The code is single-use and has already been redeemed.

To troubleshoot:

1. Double-check the code for typos.
2. Review the code's terms—look for minimum order amounts or product restrictions.
3. Make sure your cart only contains eligible items.
4. If the code should be valid but still fails, contact M&M's Customer Relations for assistance—they can sometimes reactivate a code if it's within the validity period.

Pro tip: Always copy and paste promo codes directly to avoid typos, and check the fine print for any product or order restrictions before applying.

Yes, M&M's promo codes often come with restrictions on eligible products or order types. For example, some codes are only valid on select items, while others require a minimum purchase amount (e.g., "$200 min order" for sitewide codes).

Common restrictions include:

• Only certain flavors, sizes, or personalized products qualify.
• Some codes are sitewide, but most are limited to specific categories or collections.
• Minimum order values must be met before the code applies.
• Codes may not apply to sale or clearance items.

Always check the code details before shopping, as these restrictions are a frequent reason for codes not working.

Pro tip: Filter your shopping by eligible categories or use the code on a larger order to meet minimum spend requirements for the best chance of success.

If your discount doesn't show up after entering a valid promo code, first ensure the code was entered correctly and your order meets all requirements. Sometimes, the discount won't apply if your cart contains ineligible items or doesn't reach the minimum spend.

Steps to resolve:

1. Double-check the code for typos.
2. Review the code's terms and ensure your cart qualifies (e.g., correct items, minimum order value).
3. Remove any ineligible products and try again.
4. Refresh the page or re-enter the code.
5. If the issue persists, contact M&M's Customer Relations for help—they can verify code status or reactivate it if needed.

Pro tip: Always review your order summary before finalizing checkout to confirm the discount has been applied.

If your promo code says it's expired but you believe it's still valid, it's possible the code was deactivated due to technical issues or account-specific problems. M&M's terms state that codes can be deactivated if certain requirements aren't met, but they may be reactivated by contacting Customer Relations within the validity period.

Here's what to do:

1. Double-check the code's expiration date and terms.
2. Ensure you haven't already used the code (some are single-use).
3. Contact M&M's Customer Relations with your code and order details—they can often reactivate the code if it's still within the valid period.

Pro tip: Take a screenshot of the error and your cart to speed up support requests and increase your chances of a quick resolution.

No, M&M's typically only allows one promo code per order. This is a standard policy for most online merchants and is often stated in the code's terms and conditions.

If you try to enter a second code, you'll likely see an error message such as "Only one promo code can be applied per order." Choose the code that gives you the best discount or value for your purchase.

Pro tip: Compare available codes before checkout to maximize your savings, and use the one with the highest discount or best perks for your order.

If you forgot to enter your promo code before completing your M&M's order, you generally can't apply it retroactively through the website. However, you may be able to get help by contacting M&M's Customer Relations promptly with your order number and the promo code.

Steps to try:

1. Contact Customer Relations as soon as possible after your purchase.
2. Provide your order details and the promo code you intended to use.
3. Request a price adjustment or cancellation so you can reorder with the code.

Success varies, but acting quickly gives you the best chance.

Pro tip: Always double-check your order summary before payment to ensure your promo code is applied and the discount is visible.

Yes, M&M's promo codes often exclude certain products, brands, or categories. Common exclusions include sale items, limited-edition products, or personalized gifts. Codes may also require a minimum purchase amount and cannot be combined with other offers or used for gift card purchases.

Typical restrictions:

• Only valid on select items or categories.
• Minimum order value required.
• Not valid on prior purchases, gift cards, or with other discounts.
• One-time use per customer.

Always read the fine print for each code to avoid disappointment at checkout.
