Hi @oanhtran1804,
Thank you for contacting us about our WooCommerce Extra Product Sorting Options plugin. We appreciate the feedback!
Organizing by price + shipping may not be possible. Shipping information is usually not available yet when the product sorting options are loaded. This would require we always have each customer’s delivery address. There would likely be performance issues as well. Unfortunately, this option is not likely to make it into the plugin.
You can currently organize by best selling items first, though. Using the sort by popularity option available in WooCommerce core will work for you here.
Anything else I can help with?
Cheers,
Ian
