More than twice I have received invitations from Google to take advantage of the Adwords program, some of which have been $650 USD worth. However it's until today I would like to use Adwords for a specific niche site, but I have not received any invitation for the past two months, does anyone knows if there is any running at this time?
Google randomly send vouchers if you have subscribed at their site its really hard to say when is the next promotion coming.
