Probably you haven't checked the abusive pricing at WooComemrce.com! You need a paid plugin for almost everything - like product brands and extensions to their "free" Storefront theme - to implement basic functionality like blog support, payment methods, subscriptions, membership, etc. Plus, all this is considering your time being worth $0/hr, which is not the case even in the world's poorest country! All the headaches, the expensive hosting you need (you can't run WooCommerce on a cheap server), the maintenance, etc. - WooCommerce has become one of the most costly platforms. In addition, when you have to do something yourself, you are faced with the lack of the documentation and using the tables designed for posts to be abused for all kinds of other stuff - you can really use SQL, but you need to use PHP code to even do basic DB queries!
