PrestaShop Variable Shipping Carrier
Sometimes complex shipping and handling rules make it impossible for customers to place orders in PrestaShop. Lack of instant shipping quotes, huge quantities and large weights, limited shipping addresses, etc. And while PrestaShop administrators are able to create orders manually via the back-end, these manual orders are still subject to the same shipping carrier rules.
The PrestaShop Variable Shipping plugin for PrestaShop 1.5 and above adds a variable shipping field to the Add Order screen in the back-end so that administrators can set a custom shipping price for an order they are creating.
The plugin is open-source and contributions are welcome via github.
