Hey Harper Promo Codes & Coupons September 2025

A Hey Harper promo code might not work at checkout if it doesn’t meet specific requirements, has expired, or is restricted to certain products or users. You may see error messages like “code not valid for items in cart” or “expired code” if the code’s terms aren’t met.

Common scenarios include:

• The code has expired, even if it’s still listed on some coupon sites.
• The code is only valid for first-time customers or specific products, and your cart doesn’t qualify.
• Minimum purchase requirements aren’t met.
• The code has already been used or is single-use only.
• The code is case-sensitive or entered incorrectly.

Here's how to troubleshoot:

1. Double-check the code’s terms and expiration date.
2. Make sure your cart contains eligible items and meets any minimum spend.
3. Confirm you haven’t used the code before (some are one-time use).
4. Enter the code exactly as shown, without extra spaces.

Pro tip: Always check real-time success rates and recent user feedback on trusted coupon sites before applying a code—Hey Harper codes can change frequently and some are single-use or product-specific.

These error messages indicate that your promo code doesn’t match the current contents of your cart or has passed its expiration date. “Code not valid for items in cart” means the code is restricted to certain products or categories, while “expired code” means the code is no longer active.

To fix these issues:

• Review the code’s terms—some codes exclude sale items, bundles, or specific collections.
• Remove ineligible items from your cart or try a different code.
• If the code is expired, look for a newer, active code on reputable coupon sites with live success tracking.
• Double-check for typos or extra spaces when entering the code.

Pro tip: If you see an error, try switching to another verified code with a high recent success rate—Hey Harper shoppers often share which codes are currently working.
