What happened with the prices!?

I got scammed for epwr-black and I checked
how much it costs and I said wow. Then I checked prices of other items and I said wow. Can someone tell me if it was a rich man selling items for cheap or something else?
Thanks for reading.

It’s all the 100s of dupes in the game.
Anything that was rare and you buy now is most likely a dupe .

There is no way to tell the difference
