WooCommerce Volume Discount Coupons is an extension for WooCommerce, providing automatic discounts and coupons based on the quantities of products in the cart. Tested with the latest versions of WordPress and WooCommerce, even though those might not yet appear under Compatible With on this page. Volume discounts are normally of little use unless customers are made aware of them. This extension provides an excellent solution to this need, allowing to display discounts directly on products when they apply.
