Don't get me wrong. If it were someone actually inviting discussion like "As someone from Belgorod with Russian speaking family living in Ukraine, I fear for their safety under the current regime" that would be one thing. But more often than not, it's usually something like "Russia's victory is at hand Those Ukrainian groomers will be crushed" or some other prop that is there more to be spam than discussion.
I've actually appreciated the communities here are less echochambery than on reddit. But still it kinda feels like I have to wade through more shit than usual here, and these are in comment sections far smaller than reddit.
Hard Off and Book Off are great if you want good prices. They are thrift stores, and tend to price with that in mind. Of course rarity does apply but I've never spent more than 3000y on a single item at my local location. Pricing does differ from place to place, and the rural ones tend to be cheaper.
Also from my memory, the Akiba Super Potato are way over priced, but the one in Ikebukuro tends to have better deals.
