My charger has stopped working. I have AppleCare. How do I go about getting a new charger?
You can always initiate service from https://locate.apple.com and choose your provider of choice. The online self service is much, much better now, so starting with Apple support is often the fastest way for you to get things through the hoops and to a technician to do the exchange for you if a mail in exchange isn't offered.

In your case, you can direct the service to Ireland at https://locate.apple.com/ie/en/ and just click the box that says service.



Not all resellers also provide service, so doing a little digging usually saves you a trip and some time.
