Nintendo UK has confirmed that from today you can log into the Nintendo website using your Nintendo Network ID or Club Nintendo account if both are linked. If you decide to do this then Nintendo is rather generously giving out 750 Stars which can be redeemed from the Stars Catalogue. You can log in, here.

You’ll receive 750 Stars, which can be redeemed for items in the Club Nintendo Stars Catalogue! You can choose from items such as download codes for games (some of which are available for just 600 Stars), soundtrack CDs, and much more!

Logging in with your Nintendo Network ID will also log you in to Club Nintendo, and vice versa.
