you can use coupons if you make multiple ids for the same site. One coupon accepted for one id. For that make multiple adwords account for same website and then use respectively

I will work on it, hope it will have positive feedback this time. but still, you will have to wait if these coupon will be accepted or not.

Recommend NOT doing this. It's against Google's TOS and you can quickly find your account banned and/or site de-listed.

Google Vouchers are intended for people NEW to Google Adwords. It used to be that the vouchers were setup as one per ID, but they are now setup as one per domain. Google detects the landing page being used. If you have multiple accounts with the same landing domain, you will be banned.

Google, at least in October & November 2011, was generous enough to provide people warnings - but from what I've read on the various black hat forums, the warnings are now very few and instead they're being blocked/deleted in bulk these days.

Any attempt to game the system for $75 or $100 is not worth the risk. I'm all for coupons and discounts, but that's not what this is - this is exploiting the system. Google now manually reviews all adword account signups and because of the actions of people setting up multiple adwords accounts, Google now manually reviews adwords ads/campaigns prior to going live.

You're taking a risk - don't do it - you will be caught if you try to game the system.

Absolutely right but that's the only solution if you can bypass the system..

If you're looking to cheat the system, I encourage you to create multiple IDs and get your site(s) removed from the index. Purposely trying to exploit the generosity of a company giving you $50-100 of advertisement, in my eyes, SHOULD be punished.

Creating multiple ID's is not a solution - it's a death sentence.

Looks like you guys mistaken my original intention. I was thinking of getting Google Adwords vouchers and distribute to clients like what the big guys do. It's nothing of the sort you guys are thinking of.

Yeah Google has made changes recently, you can only use the voucher on a new account within 14 days.
