My cheap tablet doesn't want to smoothly render the linked site but going by the comments, it doesn't answer its own question. I was, however, asking myself the complete opposite question the other day, when browsing Aliexpress. Why are things so cheap? I think I know some of the answers (economy of scale, cheap labor) but still. I was looking for ESP32 related things, and I can get a very sophisticated, tiny little computer, delivered all the way from the other side of the world to my house (Canada) for the price of a coffee at Tim Hortons. So yeah, why are things so cheap?
