Fixed Rate to 20kg then X per kg after?

Is there any way to support this senario...
Fixed Rate to 20kg then X per kg after.

So a courier charges a fixed rate upto 20kg then a fixed rate per kg thereafter.

Is this possible in zen either with the standard shipping modules or a contribution at all?
I guess the fixed rate upto 20kg part can be done using the table rate, not sure about the fixed rate per kg thereafter.
Any help appreciated.

Are you trying to say:

$7.50 up to 20kg ... and over 20kg use 7%

Hello Ajeh... do you ever sleep :)

Not a percentage but a fixed amount so for example

Upto 20kg costs $50, and each additional kg thereafter costs $5 more.

So 20kg costs $50
21kg costs $55
22kg costs $60
etc.

For that you would need to customize a shipping module to calculate the weight and set the cost at $50 for <= 20 and then at
build a calculation to charge the $5.00 for each 1kg over 50 ...

Ok, thanks for the reply.
Short answer to my question is no then ;)

I have achieved the same with one mahooosive array using the table rate for now.:blush:

A massive array works ... or taking the time to customize a shipping module so you don't need to worry how high the weight gets and be concerned that the order might go over that weight ...

NOTE: be sure to set the Maximum Weight in the Shipping/Packaging to something like 50000 so that your weights do not exceed that amount or it will divide the weight into separate boxes and give incorrect charges ...
