we dont have zip/postal codes! it wont let me order from the site without one?

I'm trying to order a pair of boots from "columbia sportswear company", and it says to enter my zip/postal code - we don't have them in Ireland (except Dublin) .. i tried "0000" "1234" and "xxxx", even my county, but it's not working any ideas???

The North Face and Columbia sportswear?

How can The North Face and Columbia Sportswear companies differ from another?

Where can I buy Columbia Sportswear company fabric?

I know this is probably a long shot, but I was wondering where I could find the omni heat fabric Columbia Sportswear company uses. Its the silver dotted fabric on their new line of coats and jackets. www.google.com/imgres?imgurl=strayjournal.com/wp-content/uploads/2010/10/omni_heat_dots.jpg&imgrefurl=strayoutdoors.com/columbia-puts-space-blanket-technology-in-winter-outerwear&usg=__usjmqWrNv1DRzxnggrHU3ecSv4E=&h=328&w=560&sz=42&hl=en&start=0&sig2=H47ieENIjnx6UyVvGAyWtg&zoom=1&tbnid=CbisMAQa17J3IM:&tbnh=121&tbnw=207&ei=3B9QTY6RKcH68AbCvqmvDg&prev=/images%3Fq%3Dcolumbia%2Bomni%2Bheat%26um%3D1%26hl%3Den%26client%3Dfirefox-a%26sa%3DN%26rls%3Dorg.mozilla:en-US:official%26biw%3D1680%26bih%3D897%26tbs%3Disch:1&um=1&itbs=1&iact=rc&dur=289&oei=3B9QTY6RKcH68AbCvqmvDg&esq=1&page=1&ndsp=32&ved=1t:429,r:27,s:0&tx=193&ty=38
