Based on your country please check the coupons for Adwords like this..
If you are from India www.google.co.in/adwords/coupons/
Replace the domain with your google country domain and enter your email address to get your coupon code.
*I'm not sure that it will work for all countries. I have checked the above countries it is working fine.
