so its mean my aws acc can live longer ? will still alive until the credit is reached 0$ ? when the balance still has balance my acc will not get ban ?
It has nothing to do with how long your account lasts. This is a legit event code does not get you banned for using. It is all within rules of amazon. So no downside to account by using these codes.
You get 100 dollars of credit that lasts till: DEC 31, 2017. So if you buy now you have a long time to spend on AWS products. Only thing is they don't stack, so if you bought 2 you need 2 accounts. Can't put 2 of these since same event on promo code.
