Definition:
A wishlist is an online store feature that lets people save products they are interested in to view later, without necessarily adding them to their cart or starting a purchase.
It brings selected items together in an accessible place so users can return to their product pages, organise their preferences or share them with others. Saving a product expresses interest, but does not reserve it or create a commitment to buy.

What a wishlist is used for
In ecommerce, a purchase decision may involve several visits. A wishlist keeps a selection available without having to search for every item again.
Its main uses include the following:
- Saving products for later: keeping items accessible when the user has not yet decided to buy them.
- Organising preferences: grouping products by interests, projects or occasions when multiple lists are available.
- Reviewing alternatives: returning to a selection to check features and choose between different options.
- Sharing gift ideas: letting other people see the selected products when the list supports shared access.
These options depend on the store. A wishlist does not necessarily include a comparison tool, automatic alerts or gift management features.
The difference between a wishlist and a cart
A wishlist holds products that someone wants to remember or consider. A cart contains the items with which they can proceed to checkout, choose delivery options and make a payment.
The difference lies in their purpose, not in an absolute separation of user behaviour. Some people use the cart to save products, while others quickly turn their wishlist into a purchase.
Adding an item to either space does not confirm a sale. It does not usually reserve stock either: that possibility depends on the retailer’s terms.
Products in a cart are not necessarily lost when someone leaves the page. Many stores retain carts between visits, while the lifespan of a wishlist also depends on how it is implemented.
Items are usually selected through a button or icon, often a heart, on a product page or in catalogue listings. From the list, users can view items, remove them or move them to their cart.
Some stores allow people to use this feature without registering; others link it to an account. If a list is stored only in the browser, it may be lost when browser data is cleared or may not be available on another device. A list linked to an account can be retrieved by signing in.
Lists may also be private, public or accessible through a link. Sharing options should be distinguished from publication: saving a product does not mean that other people can automatically see it.
For products with variants, it is worth checking whether a particular size, colour or configuration is saved, or whether those options must be chosen when adding the item to the cart.
Price and availability alerts
A wishlist may include notifications when a product’s price drops or it becomes available again. These alerts require additional features and are not part of every wishlist.
Saving an out-of-stock item does not guarantee that it will be restocked or that the user will be notified. Likewise, prices and stock levels may change between saving an item and buying it.
Communications must respect the recipient’s preferences and applicable requirements. Using a wishlist does not, by itself, mean agreeing to advertising or remarketing campaigns.
What information a wishlist provides to a retailer
Saved products can help identify interests and show which items people consider before buying. This information can inform catalogue presentation or relevant communications, where its use is permitted.
However, a list may contain alternatives, gifts for other people or products that the user does not intend to buy soon. The number of times an item is saved is therefore not equivalent to a sales forecast.
To assess the feature’s usefulness, a retailer can examine how many people use it, whether they return to products and what purchases follow. This relationship does not, on its own, demonstrate that the wishlist caused the purchase.
Its main contribution is making it easier for users to keep and return to their selection. Any improvement in conversion or repeat purchasing must be assessed for each retailer, rather than presented as a guaranteed result.
