OK spent a couple hours working on this and reading the forums, and I think I'm missing something obvious:
Would like to charge $0 shipping if shipping to Canada and the order is over $50. Would like to charge $10 to Canada if under $50.
Would like to charge $20 shipping to US if order under $100, $10 for $100-500 and free over $500
Would like to charge $20 shipping to UK if order under $500, $10 for $500 to $1000 and 0 for over $1000.
Some items are always free shipping no matter where.
Now:
Have enabled zone rates:

And have enabled FREE SHIPPING!
Help please. So frustrating to be so close yet so far. Thank you very much in advance.
