Hi,
I dunno if this would help you, but it helped me. There is a plugin named “WooCommerce Table Rate Shipping” by Mangohour that works well with figuring out shipping. It’s free and it helped me get my shipping right. It says it can do it by weight so maybe you could try it out. 🙂
Hi,
Very late on this post but hope it might help someone :), Premium Matrix Rate plugin allows admin to define the custom multiple shipping rates according to need.
1) It allows admin to create multiple table rates.
2) Create rate with all conditions at a time like country, region, city, zip code, weight, cart subtotal and quantity.
you will get free version from this url : https://wordpress.org/plugins/premium-matrix-rate/
