Google Adwords with Advertisement Coupon

Hi guys, I need help! I have some Google Adwords Advertisement Coupons. Does it possible to advertise my website with these coupons with newly opened Google Accounts? If so, how?
Meanwhile, I am looking for the guys who has the experience of using batch Advertisement Coupon to advertise website. If we succeeded with your instruction and help, I will reward you USD500 or more.
BTW, we have already used the two ways of Register-Manual Payment-Buy Virtual Credit Card-Recharge Coupon and Register-Automatic Payment-Recharge Coupon, however, the advertisements do not display, it says: Your keywords do not trigger any relevant ads.
If you have certain solutions, please contact me with chengweijin110@gmail.com and MSN chengweijin@hotmail.com

Coupon can be used any time, there is no restriction for that.

No matter how many coupons you have, you can only use one. Make sure you use the best coupon. I have filled in a questionaire about wanting a new coupon, but nithing happened

There is no limit...
