This plugin not only automatically changes any Amazon link on your site to use your affiliate ID, but it also changes the link to point to the user's local Amazon store.
So if your visitor is visiting from the UK they'll get a link to
Amazon.co.uk, if they're visiting from the US they'll get a link to the same product on
Amazon.com.
All you have to do is provide all your affiliate IDs.
It doesn't matter if the link is in your post, in your template or anywhere else on your page - it'll be converted automatically.
If you find this plugin helpful and it's increasing your sales, please consider
donating just £1 or more to say thanks for the many, many hours I've spent on it. I'd really appreciate it!
Disclosure:
If you don't have an affiliate account with one of the Amazon countries and leave its setting blank, the script will use mine. It'll never overwrite your affiliate IDs though, so don't worry - you'll never lose any revenue.
