This plugin adds a feature to display available coupons on the product page of a WooCommerce site. When a user navigates to a product page, this plugin scans for any available coupons and displays them in a list on the product page.
This allows the user to easily see any discounts or promotions that are currently available for that product, and they can then use the coupon code at checkout to receive the discount.
This plugin inspired by coupon listing from <a href="https://www.zalora.com.my/" rel="nofollow ugc">Zalora</a> e-commerce site.
