I’ve struggled a lot with this issue, but I finally came up with a creative solution! The thing is, Webflow only allows one discount code in the cart at a time. So, if you apply a new discount code, it replaces the old one. That got me thinking—what if the new discount code has a 0% discount? Problem solved! 🎉

Here’s how you can do it:

1. First, create a discount code in your Webflow Ecommerce settings called "NODISCOUNT" and set it to a 0% discount.

2. Then, add this script to your site to automatically apply it:
   
   <script>

3. document.addEventListener("DOMContentLoaded", () => {

4. // Checkout elements

5. const discountInput = document.getElementById("wf-ecom-discounts");

6. const applyButton = document.querySelector("[data-ecom-discount-submit]"); // Adjust selector if necessary

7. 
   

8. // Set the "NODISCOUNT" code

9. const noDiscountCode = "NODISCOUNT";

10. 
    

11. // Automatically apply the "NODISCOUNT" code

12. if (discountInput && applyButton) {

13. discountInput.value = noDiscountCode;

14. applyButton.click();

15. }

16. });

17. </script>

18. 
    

Same issue. Even after I have set the code to expire, deactivated and deleted the discount code it stays applied in checkout until I remove all the products.
