Wishlist / Save for Later

Overview

Implement persistent wishlists that survive browser sessions for both authenticated and guest users. Includes shareable wishlist links, back-in-stock email alerts for out-of-stock wishlist items, and move-to-cart flows. Guest wishlists stored in localStorage are merged with the server-side list on login.

When to Use This Skill

• When shoppers want to save items for future purchase but are not ready to buy
• When building a feature to reduce cart abandonment by offering "save for later" on cart items
• When implementing back-in-stock notifications for high-demand products
• When the brand's social/sharing strategy should include wishlist sharing
