Looking at how this currently works, how does it link towards Anime Limited? Since the yearly subscriptions come with additional bonuses specific towards the site, I initially expected that the two accounts would be linked in some way like with a shared account. However since you need to make a new account, will there be some form of linking between the two?
We have some back-end magic going on there - provided you're using the same e-mail account on both services we can ensure that your shop account is eligible for any shop-related bonuses along those lines.
If you've used different e-mail addresses across the two systems, just let us know and we should be able to fix things up for you!
