Two differant flat rate shipping prices?

Sorry if this has been asked before, I've searched online and couldn't find any solutions.

I'll be shipping using flat rate boxes, but the pricing is different for US and Canada. I want to simply have two shipping options for each category:

Shirts-
US - $5
Canada -$10

Other-
US - $12
Canada - $20

etc...

Anyone have any ideas?

Is that Flat Rate actually a "per Item Rate" for two different categories to two different Zones?

So if I buy 1 shirt to US it is $5.00 but 3 shirts to US is $15.00?

Correct.. I don't need to do combined shipping right now.

Any help is appreciated.

Thanks!

If you could make the shipping proportional between the US and Canada on a 1:2 ration ... you could use the Per Unit perweightunit shipping module and set the zone for the US and set the Product weight to the US shipping price ...

Then clone the Per Unit perweightunit shipping module and set that for Canada ... and set the Unit Rate to 2 ...

So if you wanted $10.00 shipping in the US and $20.00 shipping in Canada, you could then set the Product weight to 10.00 and the calculation would be $10.00 per qty to the US and $20.00 per qty to Canada ...
