WooCommerce is a very powerful and popular e-commerce tool and has its own resource guide and support area. We use WooCommerce for a variety of reasons but most of all for the flexibility it offers. You can sell products of your own or affiliate, sell tickets, manage inventory, offer coupons, sell memberships, track orders, record sales, manage users and so much more.
