Hi mate, Yes, you can buy it (though I'm not too sure if Google agrees with coupon selling/buying). There are a lot of AdWords coupons in the Vouchers Forum, just make sure you buy from someone with enough rep and iTrader as there has been a fair share of "dud" coupons. Also remember that they can only be used with new accounts, so they're only really useful if you don't already have an AdWords account.
