Most store owners treat “saving a product” as one feature. A shopper clicks a heart, the item goes somewhere, and you hope they come back.
But think about three shoppers. One is browsing gift ideas, one is trimming a full cart, and one is staring at a sold-out size. They want very different things. If you install the wrong tool, or all three at once, you add buttons that nobody uses.
Research from Baymard Institute shows that 42% of US online shoppers have left a cart because they were “just browsing / not ready to buy.”
This post explains the job each feature does, when it pays off, and which one to add first for your type of store.
Each feature solves a different shopper problem
Here is the short version:
- Wishlist: “I like this, but I’m not buying today.” It works on product and category pages, before the cart.
- Save for later: “I want this, just not in this order.” It lives in the cart and moves items out without deleting them.
- Back-in-stock alert: “I’d buy this now, but you don’t have it.” It only shows on sold-out products.
The trigger is different for each. A wishlist catches interest. Save for later protects an order that’s already forming. A stock alert catches demand you can’t fill yet.
Ask yourself: where do shoppers drop off on your store? On product pages, in the cart, or on sold-out items? Your answer points to the right feature.
Wishlists help browsers, gift buyers and slow deciders
Many shoppers aren’t ready to buy on their first visit. Baymard puts the average cart abandonment rate at 70.22%, based on 50 studies. That’s before you count people who never add anything to a cart at all.
A wishlist gives those shoppers a reason to come back to your store instead of a search engine.
Wishlists work best when:
- Your catalog is large and shoppers compare many items over days.
- Products are gift-friendly, so people build lists to share with family.
- Prices are high enough that shoppers wait for payday or a sale.
The big mistake is the login wall. Baymard found that 75% of sites make shoppers create an account before they can use save features. Many shoppers won’t sign up just to save one item. Let guests save first, then ask them to log in later.
This matters more before Black Friday. If shoppers save items now to wait for deals, a login wall loses those lists before the sale starts.
I’d start with a wishlist for almost every store. It’s the one feature that helps people who aren’t ready to buy, and that’s most of your traffic. Back-in-stock alerts get more credit than they deserve. If you can’t say when an item is coming back, a signup form just delays the moment the shopper goes elsewhere.
Save for later keeps the cart clean without losing the item
Picture a shopper with five items in the cart. The total is too high, so they want to buy three today. Without save for later, their only choice is to delete two items.
Deleted items are easy to forget. The shopper may never find them again, and you lose a sale that was nearly made.
Save for later fixes that with one link next to each cart item. The item moves to a “saved” list below the cart, and the shopper can check out with the rest.
This feature pays off when:
- Shoppers often buy several items in one order, such as clothing, beauty or home goods.
- Carts get large, and shoppers trim them before paying.
- Shoppers come back often, so the saved list gets seen again.
If your average order is one item, save for later does little. There’s nothing to trim.
WooCommerce doesn’t include save for later out of the box. If you already run a wishlist, check whether it lets shoppers move cart items to the list. That can cover most of the same need without another plugin.
Back-in-stock alerts only help if you restock
A stock alert lets a shopper leave an email on a sold-out product. When stock returns, they get a message.
That sounds like a sure win. Baymard’s testing tells a more careful story. When shoppers were told a product was out of stock, 30% were likely to leave and look for it elsewhere. And “email me when in stock” buttons performed poorly in testing, because they don’t create the same commitment as placing an order.
Baymard’s advice is to use alerts as a supplement, not your main fix. For items that will be back soon, it suggests letting shoppers order anyway with a longer delivery estimate. Baymard found that 68% of sites don’t allow this.
Alerts make sense when:
- You restock the same products on a regular schedule.
- Popular sizes or colors sell out before the rest.
- You run limited drops and want to measure demand.
Alerts don’t help with discontinued products. For those, Baymard recommends a clear “discontinued” label near the buy button and strong links to replacement products.
A few setup details matter in WooCommerce:
- WooCommerce sells an official Back In Stock Notifications extension. It works for guests and logged-in customers, on simple products and single variations.
- If you hide out-of-stock items from your catalog, shoppers can’t see the product, so they can’t sign up.
- Alert emails go out in batches, and the extension can’t guarantee delivery. For large lists, WooCommerce recommends a dedicated email sending service.
Which one to add first, by store type
You don’t need all three on day one. Start with the one that matches where your shoppers stall.
| Store type | Add first | Why |
|---|---|---|
| Gifts, home decor, large catalogs | Wishlist | Shoppers browse and build lists over days |
| Fashion and beauty with big carts | Save for later | Shoppers trim carts before paying |
| Limited drops, size-driven products | Back-in-stock alerts | Demand is high and restocks are planned |
| Most small stores | Wishlist | It helps the largest group: people not ready to buy |
Then follow three rules to avoid overlap:
- One saved list per shopper. If you add save for later, send items to the wishlist, not a second list. Two lists confuse people.
- One button per spot. Show the heart on product pages and the save link in the cart. Don’t show both in the same place.
- Check the sold-out state. Decide what shoppers see on an out-of-stock product: an alert form, a backorder option, or alternatives. Don’t stack all three.
Look at your own store this week. How many products are sold out right now? How many carts hold more than three items? Those two numbers tell you which feature to try next.
How WCBoost Wishlist can help
If a wishlist is your first step, WCBoost Wishlist covers the parts Baymard’s research points to:
- Guest wishlists: shoppers save items without an account, and their list merges into their account when they log in.
- Variation support: shoppers save the exact size or color they want, not just the parent product.
- Sharing: shoppers share a list by email, social post or a copied link. That’s useful for gift lists before the holidays. See our guide on sharing a WooCommerce wishlist before Black Friday.
- Theme-friendly setup: it uses WooCommerce’s basic styles and has Elementor widgets for the button and wishlist page. Setup steps are in the WCBoost docs.
