Astrid & Miyu Promo Codes & Coupons September 2025

Your Astrid & Miyu promo code might not be working due to several common issues, such as code expiration, product exclusions, or not meeting minimum spend requirements. Error messages like “Code not valid for selected items” or “This code has expired” are frequently reported.

Common reasons for failure include:

• The code has expired or is only valid for a limited time.
• The code is restricted to certain products or collections, and your cart doesn’t qualify.
• Only one promo code can be used per order.
• The code may be for new customers only, or require email sign-up or mobile alerts.
• Some codes exclude sale items, gift cards, stacking sets, advent calendars, or in-store services.
• Codes are only valid for purchases made directly on the official website, not at stockists or concessions.

Step-by-step solution:

1. Double-check the code’s terms and expiration date.
2. Review your cart for excluded items.
3. Ensure you’re shopping on astridandmiyu.com.
4. Remove any other codes and try again.

Pro tip: Always copy and paste codes directly to avoid typos, and check Astrid & Miyu’s promotions page for the latest valid offers and restrictions.

Yes, Astrid & Miyu often issues promo codes that are limited to specific products, collections, or categories. If your code isn’t working, it’s likely due to product exclusions or collection-specific restrictions.

Some codes are sitewide, but others are only valid for certain jewelry lines or exclude sale items, stacking sets, advent calendars, gift sets, gift cards, or in-store services. The code’s terms will usually specify eligible products. If your cart contains ineligible items, you’ll typically see an error like “Code not valid for selected items.”

Step-by-step solution:

1. Read the promo code’s terms carefully.
2. Remove any excluded products from your cart.
3. Try applying the code again with only eligible items.

Pro tip: When in doubt, test the code with a single, full-priced item from a core collection—this often reveals if the code is product-specific or sitewide.

No, Astrid & Miyu does not allow the stacking or combining of multiple promo codes in a single order. Attempting to enter more than one code will result in an error or will override the previous code.

Only one discount code can be applied per transaction, regardless of the type (sitewide, product-specific, new customer, etc.). This policy applies to all orders placed on astridandmiyu.com. If you try to use more than one code, the checkout will only accept the last code entered.

Step-by-step solution:

1. Choose the promo code that gives you the best value for your order.
2. Enter only that code at checkout.

Pro tip: Calculate your total savings with each code before applying—sometimes a sitewide percentage-off code beats a fixed-amount discount, especially on larger orders.

Astrid & Miyu does not typically extend or honor expired promo codes. Once a code’s end date has passed, it is considered invalid and will trigger an “expired code” error at checkout.

Promo codes are strictly time-limited, and Astrid & Miyu reserves the right to end promotions at any time. There are no published grace periods or extensions for expired codes. Customer service is unlikely to reactivate an expired expired code, but you can always check the promotions page for new offers.

Step-by-step solution:

1. Remove the expired code from your cart.
2. Look for current valid codes on the Astrid & Miyu website or trusted coupon sites.
3. Sign up for Astrid & Miyu’s email alerts to get notified of future promotions.

Pro tip: Set reminders for promo end dates and subscribe to Astrid & Miyu’s newsletter to catch new codes before they expire.
