Help linking to amazon.com / amazon.co.uk according to user’s location

(Sorry if this was discussed recently but I couldn’t find the answer using the search box.)


How easy it is to show links to Amazon according to the users location (I signed up both amazon.com and amazon.co.uk affiliate programs)

Let’s say, for example, I’d like that:
- Users from UK and Europe see links to amazon.co.uk
- All other users see links to amazon.com

Do you guys know any example I can look at? Script to detect the user’s country?

Thanks.
