USPS Shipping rates affected by Carton Size

[apollowilcox]

A recent 11# shipment going to Hawaii was quoted by the current USPS Plugin at $48. Shipstation agreed, until we entered the carton size. A little investigation showed that once the carton size was less than 10x10x10, the rate plummeted to around $18. Thats a big difference without the weight changing. (Yes, we gave the customer a credit for the difference.).

We had not previously realized that USPS was so carton-size sensitive. To avoid scaring customers off with ridiculous shipping rates, is there any way to address this issue? I've looked through plug-ins and the forum without finding any recent discussion or current fixes.

Any continuations to this discussion should use the USPS shipping method's support-thread: https://www.zen-cart.com/showthread....Support-Thread

The USPS module doesn't support dimensional shipping, but I could (in a future release) provide a notification just prior to setting the dimensions into the USPS API request so that a store could provide some site-specific customizations:

                $width = MODULE_SHIPPING_USPS_WIDTH;
                $length = MODULE_SHIPPING_USPS_LENGTH;
                $height = MODULE_SHIPPING_USPS_HEIGHT;
                $girth = 108;

                $this->notify('NOTIFY_SHIPPING_USPS_DIMENSIONS_OVERRIDE', [], $width, $length, $height, $girth);

                // turn on dimensions
                $dimensions =
                    '<Width>' . $width . '</Width>' .
                    '<Length>' . $length . '</Length>' .
                    '<Height>' . $height . '</Height>' .
                    '<Girth>' . $girth . '</Girth>';
