Marumori subscription question

At the bottom of the billing page to sign up for a subscription or lifetime membership it says

" Again, if you already have Kitsun Lifetime, be sure to link your account on the settings page first for a super sweet additional discount!"

I’ve done this and noticed no difference in price. Am I missing something or is it a bug / false advertisement?

You will get a faster response on the MM Discord. But judging by your flair here (red), it appears as monthly here so you may want to check your lifetime Kitsun status
