Hello, at the moment I am using zone rates. I only ship to the US and Canada.

For the US I have the Zone 1 Shipping Table as follows (free shipping over $99.00; flat rate of $3.50):

99.99:3.50;10000.00:0.00

As for Canada, I have the Zone 2 Shipping Table as follows ($45.00 flat rate):

10000.00:45.00

I would like to leave US shipping rate the same. But for Canada I would like to charge $35.00 for the first item and $15.00 for any additional items. Can this be done? I am currently using Zencart v1.3.9h, thank you.
