WooCommerce Name Your Price plugin displays the price field of each product and allows customers to flexibly enter the price that they are willing to pay for a product. Customer price proposals can be approved if they are eligible for the price conditions and rules that you set in the backend.

Our plugin supports assigning the coupon box popup on certain pages using WP’s Conditional tags.To handle WP’s Conditional Tags, this plugin uses eval() which is very dangerous because it allows the execution of arbitrary PHP code. Therefore, please only fill this field with proper conditional tags which are validated and/or provided by trusted developers.
