Pay What You Want lets your customers do exactly that: Pay What They Want. Inspired by Humble Bundle.
In the spirit of the app, the pricing for the app is also a one time Pay What You Want fee! All development efforts are funded by your generosity.
All you have to do is simply choose a minimum price and add a tag to your product and our plugin does the rest - it will add a special field to your product page, allowing users to enter their desired price.
