I have a limited budget too, so I buy blu-rays with anime which for sure I gonna re watch at some point. Already collected quite a few like Death Note, Code Geass, Attack on Titan, all Makoto Shinkai movies, Konosuba, That Time I got Reincarnated as a Slime, Rising of a Shield Hero, Ergo Proxy, Elfen Lied, Steins Gate + Movie, Re Zero, Goblin Slayer, Ghost in the Shell (2 movies and SAC+movie) and 3 Dragon Ball movies (Gods, F and Broly). So now saving up money for Steins Gate 0, Dr Stone, Demon Slayer, Garden of Sinners, Fate Zero, Sword Art Online. Yea, they are quite expensive, so I try to make it count. :D
