Fortnite vbucks gift card?

[cakedup]

Is there a way of buying a gift card whereby you can redeem vbucks? Ds says there is and that you get more value then buying directly through ps4. But I can't find it.

It's my god son's birthdsy today and want to get him vbucks. If not the gift card then can I buy vbucks through ds' ps4 and send it to godson on his ps4??
