<h2>Offer Shoppers Alternative Products</h2>
When a product is out of stock or no longer available, clients may leave your store without making a purchase. The Alternate Product Recommendations for WooCommerce plugin offers a solution. When products are not available, the plugin offers your customers alternate products to consider. When products are in stock, the plugin offers customers additional products to purchase.
<h2>Benefits</h2>
Customer satisfaction
Offering an alternative product lets your customers know that you care about their shopping experience.
Keep customers shopping and buying
A customer offered an alternative may be interested in that product and may buy it. Hopefully, they will continue to shop on your site instead of leaving in frustration when an item is out of stock.
Reduce cart abandonment
If a customer already has items in their cart and discovers that something they intended to buy is out of stock, they might leave your site. Offering an alternative to keep them on your site will hopefully also lead to them buying the items in their carts and/or the recommended alternate item.
<h2>How does it work?</h2>
<h3>Product no longer available</h3>
<ul class="wccom-tick-list-secondary">
<li>A user will normally see a notice saying an item is “No longer available for purchase” when they visit the product page of an out-of-stock item.</li>
<li>With the Alternate Product Recommendations for WooCommerce plugin, users will see the same notification with an alternate single item, or multiple items, to consider in its place.</li>
</ul>
