Promoting Amazon.com and amazon.co.uk products with one website?

sup boys, my website is up and running, got some sales already. The thing is, I am registered as an affiliate on amazon.co.uk and on amazon.com, is there some kind of plugin that would allow me to put two links on one product (one to .co.uk website and one that redirects them to .com according to their ip address)? For example if it sees that the ip address of the visitor is based in the US,it provides links to amazon.com?

I believe 'EasyAzon' can do that. It's a paid Wordpress plugin.

+1 for EasyAzon it will automatically do the dirty stuff for you
