From what I was told, the junior playerbase use real world cash to buy a Fortnite game card in the local stores like Big W and then use that to buy whatever cosmetic items they want from the ingame Store.
I'm not sure if they require parental permission for that.

The case I mentioned above with the scammer nephew is he was tricking his relatives into giving him money to feed his Fortnite store obsession and thus, learning dishonesty on top of another problem.





I have 28 4*, only one of which came from a paid bundle.
The rest were earned for free.

The reason I stopped paying money to Transformers Earth Wars was I tried for a few specific unlocks and just got duplicates instead.
I was specifically trying to get Snarl and Dustup in 3* (to unlock the Volcanicus and Victorion Combiners), but it never worked, so I told myself, you're paying for nothing, it's time to stop.
