This plugin was built to add a “Random” Product Sorting Order to WooCommerce with working pagination.
Other solutions I found that added a “Random” Product Sorting Order did not preserve pagination.
This plugin will sort your WooCommerce Products in random order. A random sort has a transient life of one hour. (In version 0.9.1, the duration is not a settable option. It is fixed at one hour.) Every hour a new random sort is generated. Pagination works as expected, meaning each WooCommerce Product will be diplayed once and no more than once.
This plugin requires the WooCommerce plugin.
