Setting up multiple international tlds?

[onlinesource]

I am currently trying to use a few international tld domains that I've purchased with my shopping cart which allows me to manage multiple store fronts under one dashboard.

I own mysite.au, mysite.ca, mysite.co.uk and of course, mysite.com.

When I go to sites like Cafe Press, I can see a list of international sites at the bottom. If I am viewing a product on Cafe Press such as example.com/product111.html, it looks the exact same on example.ca/product111.html or example.co.uk/product111.html for instance. Of course, the currency might change but overall, it's simply sharing products across multiple stores.

My question is, how is this not looked upon as duplicate content?

If I use a site like Geo Peeker to see what their .com looks like in Australia, they are sending people to their .au site. United Kingdom customers to the co.uk site, Canada to .ca site, and so on.

Does Googlebot or other bots crawl looking for .ca sites for Canada and so it considers .ca site content unique to Canada, co.uk site unique to UK, etc?

I just noticed that some company research results, such as .ca Amazon results appear at Google.com and not just Google.ca.

Trying to better understand how this works.

My question is, how is this not looked upon as duplicate content?

A good question and one I gave up worrying about a long, long time ago and left it to the SEs to decide whether it's duplicate or not.

I have several sites running across various gTLDs and ccTLDs and because of the nature of my industry there are bound to be some cross-overs of product lines depending in which country the widget is actually made, and that is one of the principal reasons for linking all the sites in their LHS navigation.

I have no idea how AmaBay do things but they're such mega shopping portals I doubt they even bother worrying about it.

Here's one for you. A couple of years ago Google dropped my example.com from their .co.uk results meanwhile still ranking well in the .com serps. I left it a few months and saw nothing was happening so made a duplicate of the .com on the .co.uk.

Guess what? The example.com still ranks well on G.com and example.co.uk ranks well on G.co.uk but never to be found on G.com...these sites are identical.

This should be ok. There was a discussion on this here, pay special attention to phranque's post:

Also, have a read what Google says in the last section on this page:

Two excellent links aakk9999, that's actually making me have a re-think about my .eu sites.
