Royal mail extension weight and size

[Richard Harper]

Is  there a upgrade to this.

Royal mail calculats with weight plus box size. Box sizes are small, medium and large with weight catagories in medium and large. The extension only allows for weight!

I understand i have to edit the number strings to reflect the current prices.

As i say some weight catagory's in box size share a weight class with diffrent priceses.

Is there a update to this extention? i'm on V1.1

Or has anyone in the UK overcome this problem with a work around?

Thanks in advance
