I have a question: I would like to get the Deep Freeze Bundle in Fortnite but 30 euro are too expensive for me. In the media market and so there are also codes and stuff for Fortnite. I wanted to ask if this is legal that I buy on instant gaming or MMOGA Fortnite codes? In addition, I wanted to ask if there's a risk of being banned
No, they have probably bought several codes on eial at an appropriate time and can resell them even cheaper. Such a code is in principle nothing else than other products that are on a store shelf.
Sure, that's okay and it's legal. I'm making a few pals for years.
If there's buyer protection, always use it. Because here and there can schonmal a black sheep stuck and try a key several times to sell. But in such a case, you can't activate it. Once activated, it is good. Where you bought the key, the game developer will not track it. If a key is double, only the first one can use it activated, the second gets the message that it is not valid. So you can't be banned later.
