I know someone did. I remember them wondering what would happen if they let the card expire and not pay google.
you can search on search engine and will find about VCC to verified google adwords, as i know at another forum BUT never to buy a single VCC till now
It works fine because some of my clients buy it and used for Adwords.But I don't know whether its against TOS ?

You can use Adwords with a VCC. People used to sell it here before it was banned. But it needs to have a minimum amount in it.
