I'm using flat rate shipping and I need to add a Canadian Shipping Surcharge to the order if the shipping address is Canada. So I setup a second flat rate with a base rate of $7.00 and a Conditional Action of "Check an order's shipping country". Seems to work fine on the quote screen, both my "Flat Rate Shipping" and the "Canadian Shipping Surcharge" show up. Intuiatively I assumed it was going to combine them at checkout.
The problem is when they get to the checkout screen, they have to pick one or the other. Is there a way to combine the flat rates that the order meets and combine them into a total shipping charge that is the sum of the 2? (Flat Rate 7.95 + Canadian Surcharge $7.00 = $14.95 shipping).
The surcharge is not a product so I can't do per product pricing on it. I'm stuck.
