How to get Free Promotional Code for Adwords worth $100

I have existing account with Adword which I created in initial buzz when Adwords launched by google but didnt use it as I was just explorer then.

Now comes 2012, We wanted to run a demo campaign from Adwords to know adwords effectiveness and also learn the ways to use adwords.

I noticed promotional code box in billing information, I did received promotional code from Google in the past. So I searched from google and tried them but it didnt work as they were very expired.

While searching on Internet to see if anyone has posted promo code, I didnt succeed but I did get pointer saying that Hosting providers do give some credits for free.

On searching further, I got below link, and Did as per instruction and got $100 worth free credits.
