I would like to give someone something in Fortnite but I'm afraid that they already have it and I will lose Vbucks.
I can't ask her if she already has it, it should be a surprise.
Does anyone know what happens when they already have it?
It will be shown to you when you finally send it. If you already have it, NO VBucks will be lost.
It is indicated that this person already has this item (skin (outfit), pickaxe, dance (emote), etc.). You can't give it to him again at all. That means you won't lose any vBucks. You just have to choose something else that you want to give him.
Source: I wanted to give something myself and then it was there.
Then it says that you can't give it to him because he already has this dance / skin etc. I would give him something else (if he has it), and if you don't find anything good, you could just ask if he's into something This shop is boring (if he says "Why do you ask?" then say out of boredom) and if he answers you just give him something he likes in this shop. (ask a question if necessary)
Wasn't quite the question but I also answered your question by the way
But you have to have activated 2FA if you really want to give something from the shop!
(Of course you can also decide for yourself what to give him as a gift, but that would only be an option if you can't find anything else in the shop that you think is good / nice etc.)
