The WooCommerce Cheapest & Most Expensive Product Promotions! (WCGFI) allows you to easily create promotions to apply a discount percentage (that allows you to give it even for free!) to the most expensive or the cheapest product on the cart!
HOW TO AUTOMATICALLY UPDATE THE PLUGIN
THE IDEA AND HOW IT WORKS
The idea behind the plugin is to have a tool that allows the shop admin to easily create promotions to apply a discount percentage to the cheapest/most expensive product on the cart. A Promotion will be applied according to the Cart total or if Specific products are currently present on the cart. Once detected one of these conditions, the plugin will detect the cheapest/most expensive product on the cart (or the cheapest/most expensive among a preselected set of products chosen by the admin) and will apply a discount (displayed as cart fee). Discount can be applied also according to the item quantity.
