It's That WaniKani Sale Time (Dec 18, 2018 - Jan 8, 2019)

I found in my mailbox the following:

So, I wanted to give you a heads up on a prophecy I overheard the higher-ups talking about: It’s said that this year’s Lifetime membership sale will be from December 18, 2019 to January 8, 2020 and it will be $100 (33%) off. Between paying for these robes, t-shirts, dues, room, board, and with 50% of my salary earmarked towards “Crabigatorism,” this discount will really be a crab-send to my finances, not to mention my Japanese studies.

Whereas the price tag is still $199. Should I assume $100 was a real offer I got

That means a discount of $100 from $300 to $200. There’s more on this year’s thread
But good luck and welcome to the forums!
