Wishlist is an essential feature for e-commerce businesses. Customers appreciate the ability to browse products multiple times before making a purchase, and having a Wishlist allows them to easily keep track of their desired items. With Wishlist, customers can easily compare products, use guest mode, and even merge guest lists after logging in. Additionally, businesses can benefit from the Top Products and Top Customers reports, as well as the easy installation and JS API wrapper for customer meta fields.
