I'm wanting to do a little experimenting with Adwords.
$50 and $100 credits seem to be widely available for new accounts (which I will be) - mostly if you buy something from the crowd offering the credit.
I've already checked my webhost and registrar - webhost has a $100 credit but not for my plan, and registrar doesn't offer a credit at all.
So, is there a way to get the Adwords credit 100% unquestionably above-board without buying anything? (Google doesn't just give it for the asking, I assume...)
If not, where can I get the largest introductory credit for the smallest investment?
