I didn't get any vouchers when I signed up Adwords so my advertising costs have been real money. I signed up Yahoo Search Marketing last month and got a $25 coupon, nice! Got a couple of CB sales from using that
Of course it is real money. The voucher could just be a starting point, but you have to use real money finally. You could get a $50 yahoo voucher if you visit my site( You would have to opt in though) bye, faraz
