I live in the Republic of Ireland which is served by amazon.co.uk. The rads.stackoverflow.com/amzn/click/ redirector sends me to amazon.com.
According to this article, the redirector should use IP geolocation to send you to the most appropriate Amazon site:
We have a clever affiliate redirect that geolocates the IP and redirects to the appropriate regional Amazon store (amazon.uk, amazon.ca, et cetera).
Can the Amazon link redirector be changed to redirect to amazon.co.uk for Irish IP addresses?
