Sorry wasn't getting the full picture.
Then probably just create your content with geotargeted results and just let the spiders crawl the different versions via whatever links you use between the different versions. Visitors get redirected to whatever content suits them based on their IP.
Make sure whatever linking method you use is spiderable (drop-downs with javascript redirects to be avoided if possible). Footer links like on amazon.com would be best for spiders.
If your pages are only going to contain scrapped amazon items then you are probably never going to rank to well in the
SE's unless you can gather a pretty (read: seriously) large amount of backlinks to those subdomains and internal pages.
Tough one from an
SEO perspective.
