But, I can't figure it out.
How do I setup up my shipping to do this;
Using USPS, $1 shipping per product inside the US, $2 per product inside Canada, and $3 for other international shipping.
So there are no options, if you enter a US address there is a $1 charge. Enter a Canadian address its a $2 charge. Any other address = $3 charge.
The problem is when you purchase 5 products, how do I make sure the shipping charge is multiplied by 5?
