Free shipping by import Chrome extention

Hi,

Hope you’re all safe and well?
Just found your dropshipping plugin for wordpress and Woocommerce. Just playing around for now. but its seems something that will work for me. My questions is, when I select a product at the aliexpress website that tells me free shipping to New Zealand (where I am based) and I will import that items its still giving me a price for shipping. Any idea what I am doing wrong?

cheers Rob
