Shopify multilingual cart logic and delivery messaging setup

I configured a Shopify store with full support for three languages, Ukrainian, English, and Dutch.

What was done.
1. Added dynamic delivery messages in the cart.
if the order total is below the free shipping threshold, the cart shows the delivery cost and how much more the customer needs to add to get free shipping.
if the total is above the threshold, the cart shows a free shipping message.
The calculation is based on the final total after discounts and coupons.
2. Added a top banner with the free shipping conditions, and made the threshold and text editable from the theme settings, without touching the code.
3. Implemented multilingual support, all texts were moved into locales so they can be translated per language, EN, NL, UA. This includes the cart messages.
4. Integrated the Selleasy product recommendation widget.
Placed it in the correct position in the cart, made sure it loads only once and works correctly with the ajax cart, no script conflicts.

The result is a Shopify cart with dynamic shipping logic, editable promo banner, full translation support, and product recommendations ready for multi-country sales.
