On my Godaddy account I tried to apply some coupons, but they all tell me that there is a limit to how many I can use etc. So I thought if I created another account I might be able to use them. So I did create another account with the same email address and the same credit card. But it recognized me and wouldn't let me use the coupon/s. So is that I need a unique credit card, or is it that I need to use another email address? Or both?
