If anybody is interested in learning/memorising Japanese Kanji using the popular spaced repetition website Wanikani - there is currently a sale off their lifetime membership (normally $299 USD).
I'm currently subscribed to Wanikani and i have learned more Japanese in the 8 months than I ever learned in school + 1 year of living in Japan :) It may work for you too.
(alternatively you can get 50% off their normal subscriptions (ordinarily $10USD a month, $100 USD per year) by using the code "CRAB YORI GATOR" - just tested and can confirm it works).
These guys been emailing me for awhile cant remember signing up but I got alot of accounts for Japanese study Im pretty sure also Japanesepod has an xmas special going(got 2 years premium for 100 dollars last year).
I have been using Jisho.org and other sites to prep for the JLPT
