Sending a gift voucher to the US

[XAVIER]

Hi.
My brother recently moved to the US and I need to send him something for Xmas. I was thinking of a gift voucher of some kind but I know he will send me an Amazon voucher so wanted something a bit different but that works in the same way I.e. I pay for it here and he gets it in his email Christmas day (lazy I know!)

I have tried places like Walmart, Barnes and Noble but no luck.
Any ideas welcome!!
