Coupon usage issues

I. New Customer Coupons:
Display a registration popup on the homepage. After users provide their email addresses, they receive a coupon immediately on the thank-you page, and the coupon is also sent to their email.
On the checkout page, after adding items to the cart, users can click “Have a coupon?” to enter the coupon code, click “Apply” to use the discount, and proceed to complete the checkout.

II. Abandoned Cart Coupons:
If a user adds items to the cart but does not proceed to the next step after a long time, the system automatically sends a recovery email with a coupon.
The coupon usage process is the same as for new customer coupons.

III. Existing Customer Email Coupons:
Weekly marketing campaigns tied to holidays or special events are sent to existing customers via email, including coupons.
