< Feedback on Total of all Aliexpress purchases
Maybe I'll update it, but for now you can still go to https://www.aliexpress.com/p/order/index.html (global layout), click "More orders" as many times as many goods you need to include in total (only currently displayed on page will be included) and then use Calculate func.
Any chance this will be updated to work on Ali's changed layout?
