I just got a coupon of Rs 2500 ($50) from google adwords in my gmail account but when I tried to use it, it said that "Sign Up Offer limited to one per customer". Is this because appearing because I am a registered member already and also because I have used an other coupon already months before. Please let me know if I can use the new coupon or not?
Most of the coupon is for a new register, since you are already registered so the coupon no longer good. Although been with Adwords for many years some time they still send me coupon through mail and i don't know why!!!
