Why everyone sell the same thing ?

I’ve been looking those live shows , it’s just getting annoying because everyone sells those Valentino Orlandi ( no to mention from Tjmaxx) with price tags $279, and they like 30$ in tj. Them people with Temu stuff all over, or paparazzi. I don’t get it what happened to the posh? Before you can find unique /stuff , and now it’s garbage. This freaking Jeffrey Star omg I hate it seeing all over the place. Lots of fake shows like the one Zaddy, he is the nastiest man alive and fake show, then Rueberry same thing, and twicebutnice, and swag guy - so many scammers
