Where does one buy such cheap Vostoks?

Im new to the watch thing, and naturally I've been researching and watching youtube videos, and I always see people say how Vostok watches are so cheap and all. Or that vostok has 30 dollar automatics. But where? How? What are they talking about? They are literally 200 dollars + wherever I search. I honestly feel scammed by where I live, everything has like some kind of mystical "watch tax". So where do I find those elusive "30 dollar" vostok automatics?
