What – Designing a Redeem Coupon Feature
Why – A coupon redemption feature needs to include a field for entering the coupon code, an apply button, and clear feedback on whether the coupon was successful. When a coupon is applied, the discounted amount appears in red within the pricing section to make the change more noticeable. The apply button is grayed out after a successful redemption to prevent reuse. Additionally, a confirmation message pops up to inform the user that the coupon has been successfully applied.
