I have flat rate shipping using zones. Canada zone is $16 flat rate US zone is $6 flat rate
Using warehouse shipping to assign shipping to items

If i choose my billing and address as US. or Canada off the bat, it works right, but if i CHANGE the shipping OR billing address it does not update the cart with the correct shipping. How can I have this change depending on SHIPPING address?

(PS Do not test with poster or charms, use a shirt)

Thank you for the reply. Adding shipping step back does indeed recalculate shipping. However, we have a few products that have free shipping. The checkout step shows these nicely, However, no matter how I configure the checkout shipping method it will not go past that step. If i remove the step and have it choose and submit automatically it works, but if i have it set so it shows shipping it won't go past that step if there is a free and a shipping charged item in the cart (2 diff warehouse shipping methods)

I'm sorry but I can't get it to work the way you say.
Please tell me how to set up 3 shipping methods
1 to US $6 flat
1 to US free (only for certain products)
1 to Canada flat for ANY product even if free in US

Hello,
In your case, the base solution will probably be to :
- Use a warehouse restriction for the "US free" and the product that have to be used by that shipping method
- Set the "Zone" restriction option to USA for your 2 first shipping methods and for Canada for the 3nd one.
