Hi all

I wonder if someone would be so kind in giving me a simple answer to this problem.

I am completely new to Zen Cart and have set up my UK shipping rates on the table rate, i did this ok.

My problem is that I had an order come through last night, which was great, but the customer lives in the USA and she has paid the shipping price for the UK. In the shipping bit in the side box on my website I do have a list of shipping charges and did put a note there to say customers must e-mail for a quote but she obviously did not see that and the shop has calculated her shipping cost on what she spent not where she lives.

I need to be able to set up something similar for the international shipping as well so this doesnt happen again, BUT HOW DO I DO IT?????
The answer to this MUST be in REALLY SIMPLE terms as I dont understand alot of this stuff, not sure sometimes how i got this far with it.
Any help would be greatly appreciated
