ASDA Promo Codes & Coupons September 2025

If your ASDA promo code isn’t working, it’s usually due to one of several common issues: the code may be expired, entered incorrectly, not applicable to your basket, or subject to restrictions like minimum spend or product exclusions.

Typical error messages include “This code is not valid,” “Code expired,” or “Promo code not applicable to your order.” Common scenarios include:

• The code has expired or is only valid for a limited time.
• Your order doesn’t meet the minimum spend or other requirements (such as specific products or categories).
• The code is only for new customers or certain delivery methods.
• You’ve already used the code, or it’s limited to one use per customer.
• The code is not valid in your location or for your chosen delivery slot.

Step-by-step solution:

1. Double-check the code for typos or extra spaces.
2. Review the terms and conditions for restrictions.
3. Make sure your basket meets all requirements (minimum spend, eligible items).
4. Try another valid code if the first one fails.

Pro tip: Always copy and paste promo codes directly from a trusted source to avoid errors, and check expiry dates before applying.

Yes, ASDA promo codes are case-sensitive and must be entered exactly as shown, without extra spaces or characters.

Entering the code incorrectly—such as using the wrong case, adding spaces before or after, or including extra characters—will result in an error like “Invalid code” or “Code not recognized.” This is a frequent issue, especially when typing codes manually. The promo code box on the checkout page requires an exact match, and even a small typo will cause the code to be rejected.

To avoid this:

• Always copy and paste the code rather than typing it.
• Double-check for any accidental spaces before or after the code.
• Make sure you’re using the correct upper or lower case as provided.

Pro tip: After pasting your code, check for hidden spaces at the start or end—these are a common reason for rejection.

No, ASDA does not allow stacking multiple promo codes on a single order; you can only use one code per transaction.

If you have several codes, you’ll need to choose the one that gives you the best value. Common practice is to:

• Compare the discount amounts or benefits (e.g., percentage off vs. free delivery).
• Check which code applies to the items in your basket and meets all requirements.
• Read the fine print for each code, as some may have product or spend restrictions.

To determine the best code:

1. Add your items to the basket.
2. Test each code at checkout to see which provides the largest discount or most relevant benefit.
3. Choose the code that saves you the most, considering both the discount and any delivery or product-specific perks.

Pro tip: Before finalizing your order, try each eligible code and review the updated total—sometimes a smaller percentage off can save more if it applies to a wider range of products.
