What is WooCommerce?
WooCommerce adds a full shopping cart experience to your WordPress website, and can be extended to sell tickets, memberships and courses – if you can think of it, you can sell it.
Like WordPress core, WooCommerce is completely free to use. There are paid-for addons you can use to extend it, but the base will never cost you anything. It’s secure, works flawlessly, and can handle all the sales you’re able to drive to it.
