About this plugin
Keep customers shopping when a WooCommerce product is out of stock.
When a customer lands on an out-of-stock product page, LONDOM – Out of Stock Alternatives shows a box of available alternatives at the top of the page, above the product, so they can pick another product instead of leaving.
The box lists up to 4 products (filterable):
- Your upsells first – the upsell products you set in the product’s Linked Products tab, if they are in stock.
- Then products from the most specific category – if there is room left, in-stock products from the most specific category assigned to the product, ordered by sales. A broad parent category (for example “Men”) is ignored when the product is also in a narrower one (for example “Wallets”), so suggestions stay relevant.
If nothing is available, the box says so instead of showing unrelated products. A “View all” button leads to the product’s main category (the primary category set in Yoast SEO or Rank Math, when present).
Key Features
- Alternatives above the product – Shown at the top of the product page, after the WooCommerce notices, not inside the product layout
- Upsells first, then category – Manual upsells take priority; category products fill the remaining slots
- Simple and variable products – A variable product is treated as out of stock only when all its variations are unavailable
- Add to Cart hidden while unavailable – The Add to Cart form is removed on out-of-stock products (filterable), on themes that use the standard WooCommerce hooks
- Works with your theme – Uses standard WooCommerce hooks; tested with Blocksy and Storefront. Where the box is printed can be changed with filters
- Performance optimized – Alternative product IDs are cached and checked on every page load
- Multilingual ready – Translatable on translate.wordpress.org; compatible with Polylang and WPML
- Cache plugin support – Works with WP Rocket, W3TC, LiteSpeed, and WP Fastest Cache
- Accessible – ARIA labels on the links and the alternatives block
How It Works
- Detection – The plugin detects that a simple product, or every variation of a variable product, is out of stock
- Notice and alternatives – A short notice and the alternatives box are printed above the product
- Selection – Up to 4 in-stock products: upsells first, then the most specific category
- Caching – Alternative IDs are cached and re-validated on each page load, so sold-out products are filtered out when the page is generated
