WooCommerce Name Your Price Plugin
 

The WooCommerce Name Your Price Plugin allows you to set your own price for certain products. You can either suggest a price to your consumers and possibly impose a minimum acceptable price, or you can leave the decision totally in their hands. You can also use this plugin to accept donations,make your items more accessible to a wider audience, collect information on how much clients are prepared to pay, or take variable sums for other purposes like bill payment.
