makes it possible for you to create shipping rules for boxes.
Boxes have a fixed size, and items are packed volumetrically. You can define multiple rates based on the package destination, have multiple box sizes per zone, and add costs based on box, box weight and box content cost.
When a customer checks out with items in their basket, the plugin reviews the destination of items, matches this to a zone, and then uses the rates in that zone for the calculation. Each destination and rate can have its own box sizes and multiple sets of box sizes, based on your shipping requirements. Items are packed into boxes to get a rate.
To calculate shipping correctly, you need to create your Shipping Zones and box size rates. The plugin does all calculations for you.
The box packer included with this shipping method lets you group items into packages for which you define height, width, length, weight and max-weight. Packing is mainly volume based, but also considers item sizes too.
