Think about flipping through a paper holiday catalog and circling toys or clothes you want with a pen so you can find them easily later. In digital retail, that pen circle is a wishlist. It is a personal digital folder inside an online store where shoppers save items they like but are not ready to buy just yet.

People save items for many reasons. They might be waiting for payday, planning a birthday gift list, or simply comparing options before making a final choice. Instead of adding twenty items to a shopping cart and cluttering checkout process, they tag items with a heart icon to save them safely in their account profile.

For store owners, a wishlist is a goldmine of data. It shows exactly what items are popular even if they are not selling immediately. Shops can send automated reminder emails when a wishlisted item goes on sale or runs low on stock. It transforms window shoppers into future buyers by making it incredibly easy for them to return and complete purchase later.
