questions about google adword
first question is about the adword vouchers which are being sold out here/
can i use 2 or 3 adword vouchers in my one adword account.
i listened that when we activate first time google adword with our credit card google itself sends 100 us dollars credit of adword. so if i have that credit already and add another voucher code(purchased from dp). will it add the both sums and making it 200 dollars credit. or should it first finish the first one hundred dollar creidt.
thanks in advance.
