Not sure if you understand what I mean. Let me explain in layman terms again

Let’s we have set “FREE SHIPPING” for Total orders above “USD500”.
So, when the customer select “Item 1” worth USD100, there should be a Progress bar saying “USD400″ left for FREE Shipping” or something like that..
I have attached screenshot for your reference…

Hope you understand this time around!

Let me know

Thanks,
Sagar
