[TYPO3-shop] shipping based on order total

[Simon Browning]

I've got a client who's shipping rate is basically like this:

if the order total is $1 - $10, shipping is X
if the order total is 10 - $50, shipping is Y
if the order total is $50 - , shipping is Z

Can it be done through typoscript, or will we need to work it into a 
calculation script?

Thank you.

Simon
