What is the most expensive thing to buy in Fortnite?

I'm curious, what is the most expensive item that can be purchased in the popular game Fortnite? I've heard rumors of some incredibly costly items in the in-game store, but I'm not sure which one takes the top spot. Is it a rare skin for a character? A powerful weapon? Or perhaps something entirely different? I'd love to know the specifics of the most expensive item in Fortnite and how much it costs in real-world currency.
