I have received more than $500 worth of adword coupons via email and there's one that came thru snail mail during valentines day and I am sure that some of you here might have received a lot more. I already have 3 accounts with adwords that are linked with different bank accounts and I still have more unused coupons. What do you guys do with your unused coupons? How safe is it to have multiple accounts in AdWords? I heard that other people got banned 'cause of this but other people get away with it.
