Duplicate currency page variations?

Hi guys,

I have duplicate category pages across a ecommerce site.

For the currency based pages i was wondering would it be best (or easier) to exclude them in the robots.txt or use a rel canonical?

If using the robots.txt (would be much easier to implement then rel canonical) to exclude the currency versions from being indexed what would the correct exclusion be?

Would it look something like:

Disallow: */?currency/

Google is indexing the currency based pages also:

I would suggest using rel canonical tag, as this is what it was intended for:

Thanks Woody,

Ok, any issues with adding no-index tag - Disallow: */?currency/ to robots.txt?

Rel canonical would be very difficult to implement (CMS is Wordpress) to implement and super time consuming.
