Free $50 Adwords vouchers link

I found this link where you can request a free 300 DKK ($53) voucher for AdWords:
https://services.google.com/fb/forms/updatenordicsda/

It is a very new campaign, and should work until the end of next month.

I don’t know if you can use the Gmail tricks (numbers and the “.”-method), but if you have your own domain name you might be able to use a catch-all email address to get an unlimited number of vouchers
