Define sales points and let WordPress & WooCommerce increase the price of the product after a defined amount of sales. WooCommerce 3.0 is requested. It won’t work on version below 3.0. This plugin will directly change the Regular Price of your product, it won’t save the regular price since it will be changed directly. This is done so that you may also delete all the sales points but retain the last price change of your product. Under the product price, there will be a notice for your customers that the price for this product will increase after X sales.
