Choose default shipping method based on price

Zen-Cart 1.3.8a
Shed loads of add ons.


Not sure if this has already been covered, I have done a search but not found my answer, so apologies if it has.


For my shipping options, I have more than one flat rate option - i.e for UK I have standard 1st class, recorded 1st class and special delivery options (all fixed price).

I need to "suggest" the shipping method to be used depending on cart value (but still need to have option for customer to change).

By this I mean for normal lower priced items suggest recorded delivery by having the recorded box selected, but for higher value items (including cart totals) I would like to have the special box selected.

Is there a way to do this based on the total value of the cart?

The shipping method set by default is managed in the shipping.php class on the:
function cheapest

You could customize that differently as you need it ...
