Not sure of the details you are looking for, but I'll give it a shot.

By "Serve Money" I just mean an account on serve.com. It links directly to your bank account and that's how you load the money. You can also load money via GDMP.

As for gift cards, I'm just trying to figure out if there's any gift cards I can buy online to exchange for BTC.

Hopefully this helps.

Thanks.
