You can let your users determine the price of the product and receive donations.
Sites like Priceline have created a business on this idea and take advantage of the power of the sale system based on how much users are willing to pay to accommodate their needs.
With YITH WooCommerce Name Your Price Nulled , you will offer your users the freedom to pick a price, in order to understand the true market price, or simply having a different approach to sales. The plugin offers you also to suggest an ideal price to users, and to set a minimum and maximum price for your products.
It is all about market laws and a psychology: satisfied customers need to “pay back” somehow the service or the product that made them happy.
They can do it with a donation, or maybe, paying something more for the next product they are going to purchase.
Let’s make an example: you sell an ebook that costs sixteen dollars, but you also offer your users to support your business adding more dollars, because your products have improved their life in the past.
