WooCommerce Wholesale Prices
A extension for WooCommerce, which adds multiple levels of wholesale pricing to your store depending on the user role.
An extra field will be added to your product data tab for each role, where you can add a “wholesale” price. This is applied to simple products, as well as variations.
Once a price has been entered, it will override the default product price with the new wholesale price you entered for that role. Wholesale prices will only be shown if the current user has a role that has been specified in the options page.
