Japanese language learners: Bunpro is doing a Black Friday sale on lifetime memberships. They only do this sale twice a year, so it's a good time to save if you've been thinking about it. I've been using them to learn grammar for awhile now, and it's a great resource - their lessons are detailed and nuanced, in a way I find very easy to understand, and they have a lot of great sample sentences.
Lifetime memberships are normally $150, but it's $120 during sale periods.
