AOP Promo Codes & Coupons September 2025

This error usually means the promo code is invalid for your order, even if you entered it correctly.

AOP promo codes often have restrictions such as being valid only for select items, new customers, or a minimum order value. If your cart doesn’t meet these criteria, you’ll see errors like “Enter a valid discount code” or “Code not working.” Codes may also be single-use per customer or have an overall usage limit, so if you or others have used it before, it won’t work again. Double-check for typos, but also review the code’s terms—sometimes, codes are only for specific collections or products, or they may have expired.

Pro tip: Always check the promo code’s details and make sure your cart matches all requirements before applying it to avoid last-minute surprises.

Yes, AOP promo codes often exclude certain products or collections, and these restrictions are usually listed in the code’s terms.

Many AOP codes are limited to select items or collections, which means they won’t apply to every product in your cart. You can usually find these exclusions in the promo code’s fine print or on the AOP promotions page. If you’re unsure, try adding the code at checkout—if it doesn’t apply, the error message may specify which items are ineligible. Some codes are also restricted to new customers or require a minimum order value.

Pro tip: Before shopping, review the promo code’s terms or test it with different items in your cart to quickly identify what’s eligible.

If your AOP promo code is valid but won’t apply, technical issues like browser settings, device compatibility, or private browsing can sometimes interfere.

Promo code fields may not work properly if cookies or JavaScript are disabled, or if you’re using private/incognito mode. Try these steps:

1. Switch to a standard browser window (not incognito/private).
2. Enable cookies and JavaScript.
3. Clear your browser cache.
4. Try a different device or browser.

If the problem persists, double-check that your cart meets all promo code requirements (product eligibility, minimum order value, new customer status, etc.).

Pro tip: For the smoothest checkout, use a mainstream browser (like Chrome or Safari) with cookies and JavaScript enabled, and avoid private browsing when applying promo codes.

To check if an AOP promo code is expired or already used, try entering it at checkout—AOP’s system will display a specific error message.

If the code is expired, you’ll typically see a message like “This code has expired” or “Code not valid.” If you’ve already used the code, the message may read “Code already used” or “Limit reached”. Some codes are single-use per customer or have a total usage cap, so once those limits are hit, they stop working for everyone.

Pro tip: If you get an error, try a different code or check AOP’s latest promotions page for current, unused offers.

AOP promo codes may not work for several common reasons:

• The code is expired or has reached its usage limit.
• It’s restricted to specific products, collections, or new customers only.
• Your order doesn’t meet the minimum order value required.
• You’ve already used the code, or it’s limited to one use per customer.
• The code has typos or extra spaces.

Error messages like “Enter a valid discount code,” “Code not working,” or “Code already used” will appear depending on the issue.

Pro tip: Always review the promo code’s terms and ensure your cart matches all requirements before applying.

Yes, AOP frequently offers promo codes that are valid only for certain products, categories, or require a minimum order value.

For example, some codes provide discounts on select curriculum lines or collections, while others may require you to spend a certain amount to qualify. Restrictions often include single-use per customer, new customer eligibility, or limits to specific product groups. Always read the promo code’s terms to understand what’s included.

Pro tip: Look for the promo code’s details on the AOP site or in the offer email to ensure your order qualifies before you check out.

AOP typically allows only one promo code per order, so you’ll need to pick the code that gives you the best value.

When you try to enter a second code, the system will usually replace the first one or show an error. Compare available codes for the highest discount or the one that applies to the most items in your cart. Some codes may offer a percentage off, while others give a fixed amount or free shipping—choose based on your order size and contents.

Pro tip: Before checking out, test each code to see which gives you the biggest savings, and remember to factor in any minimum order requirements or product restrictions.
