hello,
I have a couple of questions if you don't mind
You have to enter a default address in your admin area. This would mean that they still only get one option via international and national? At the moment when customers checkout only international comes up, what if they are national? This would not fix the problem?
I have found with other carts, that the customer chooses their shipping needs.
Secondly, will this world with custom charges. I have inserted royal mail into the shipping options. It will be the only option with international and national.
