The Tool Behind the Magic: “bt_dynamic_courier_rates”

In simple terms:
👉 You can decide which courier options to display and which ones to hide, based on your own rules.
Step-by-Step: Automatically Selecting the Cheapest Shipping Rate
Here’s how you can implement this on your store:
1. Add This Code to Your Theme’s functions.php File or a Custom Plugin:
2. What This Code Does
-
Finds the courier option with the lowest shipping cost from the available list
-

-
Shows only the cheapest shipping option on the checkout page
In short, it removes decision fatigue for customers and gives them the best deal right away!
Real-World Example:
Suppose your cart offers these courier options:
Courier A : $5.00

No manual selection needed!
