Zip code RANT !!!!!!

When selling parts from Canada and someone is asking for shipping, would be nice to have the State and Zip Code simply because Canada Post uses the State and couriers use Zip Code and city/town for getting rates. But after saying that it only takes a minute to to get either as mentioned before.
Just my 2 cents

Sure - it only takes a minute, but when your searching through 3 dozen listings, that's a minute for each listing. It's just a PITA. Not to mention, I sometimes get my hopes up when I see something good, only to find out the guy's on the other side of the continent.
