OpenCart Community

Current Version: v2025-3-21 (release notes)

OpenCart Versions: 1.5.1.x - 4.1.0.x

To Purchase: Visit Clear Thinking or opencart.com



This Order Total extension allows you to automatically apply your store's lowest eligible shipping cost to the customer's cart. Once the customer selects a shipping method, the selected shipping cost will override the automatic shipping cost, which will then disappear.

• Upload and go — modifies no core files.
• Take advantage of the built-in extension updater. All that's required is to enter your current license key and click "Update".
• Display to your customers their cart total including shipping as soon as they add a product to their cart.
• Customers can select a shipping method during checkout as normal.
• Properly uses the customer's checkout address if entered, their account address if not, and the store's default address if not logged in.
• Displays the correct shipping method title for the lowest shipping cost, so customers know what shipping they are being given.
