Can I pay with eShop credit in Fortnite VBucks (Nintendo Switch)?

Aloha:-)

I received an eShop credit card for my birthday. Can I use the credit to buy or pay for VBucks in Fortnite?

Yes, you can do that.

That's fine

I would be but you would buy the one package I Shop instead of V-Bucks, there's such a skin with a backpack and pickaxe And 2 styles (you don't have to like it) + 600 V-Bucks for only 3.99 and that is very good because you get skin (you don't have to like it) with a pickaxe and so on, plus the V-Bucks which is good because otherwise you would have to pay more for the number of V-Bucks if you buy 7.99 V -Bucks you get 1000 V-Bucks and for half that you get 600+ skin.
