Is 'Zones' the answer?

I use the USPS module for shipping worldwide. It works great.

Unfortunately, the UK postal system is not so great. In fact, they have cost me quite a few hundreds of dollars in lost shipments.

I want to require UK customers ONLY to use a trackable method of delivery via USPS (Int'l Express or priority or something yet to be determined). Is this a job for the 'Zones' module?

Any other recommendations?

thanks.

USPS has several selectable choices for National and International ...

If you want to alter what is available from the Internation choices only for UK customers then you would need to customize the code to further filter out what is available to them ...

If you want to use a totally different Shipping Module for the UK and turn off the USPS shipping module you could customize that shipping module further to not display when the shipping address is to the UK ...
