I just got to level three a few days ago. I was pleasantly surprised to find an email from the WaniKani team for FREE stickers! Well, they just came in today and I was so excited when I realized it was from them. I just wanted to say thank you guys for a wonderful product and an awesome community. I’m excited to be learning Japanese with yall!
My stickers are on their way right now. Damn it I spoiled the surprise 
I’m just ordering mine now ten months later.
