Aer Promo Codes & Coupons September 2025

AER promo codes may not work for several reasons: the code may have expired, it might not apply to the specific products you're trying to buy, your order might not meet a minimum spending requirement, or there could be a simple typo in the code. You might see error messages like “Invalid code,” “Code expired,” or “Code not applicable to items in your cart.”

AER often limits codes to certain products or collections, or requires a minimum order value. Many codes can only be used once or are only for new customers. Double-check the code for errors, make sure your cart meets all the requirements (like a minimum purchase amount or eligible items), and confirm that you haven’t used the code before. Some codes are only valid during specific promotional periods or for certain items, such as "20% off selected products" or "70% savings on specific products."

Always copy and paste codes directly and check the terms on the AER checkout page before placing your order to avoid common errors.

If your AER promo code appears as expired but you believe it should still be valid, first double-check the expiration date. Many codes expire at midnight on the listed date, and the time zone might be different from yours. The error message usually reads “Code expired” or “This promotion has ended.”

See if the code was for a flash sale or a limited-time promotion, as some AER codes expire quickly or are only valid for a few hours. Also, make sure you haven’t already used the code, since many are single-use per customer. If you’re sure the code should work, try clearing your browser's cache or using a different device, as technical issues can sometimes cause problems.

Sign up for AER’s email list or follow them on social media to get updates on new codes and avoid missing out due to unexpected expiration.

AER sometimes allows promo codes to be used on sale items, but most codes exclude already discounted products or only apply to full-priced items. You’ll often see an error message like “Code not valid on sale items” if you try to use a code on a sale item when it’s not allowed.

Some sitewide codes (like “20% off store-wide”) might work on both regular and sale items, but high-value codes (such as “70% off specific products”) are usually limited to specific items and can’t be combined with other offers. Always check the terms of the promotion, which are usually listed on the code’s details page or during checkout.

Test your code on sale items in your cart before checking out, and look for sitewide or “store-wide” codes for the best chance of saving on sale items.

Most AER promo codes are single-use per customer, meaning you can only use them once per account or email address. If you try to use a code more than once, you’ll likely see an error message like “Code already used” or “Limit reached.”

Some codes, especially those for new customers or first purchases, are strictly one-time only, while others might have a limit on how many times they can be used in total. Occasionally, AER releases codes with unlimited uses for a short time, but these are rare and usually tied to major sales events.

If you want to use a code more than once, look for new codes released during seasonal sales or sign up with a different email address (if AER’s terms allow it).

Aer may occasionally offer discount codes, but currently, there are none available. However, customers can still save money by taking advantage of other promotional offers or sales available on the website, or by using credit card points to make purchases.
