can I use to pay last bills or for new consume?
you send vouch or discounts for trusted/senior users?
Yes 100 percent legit they were from a Amazon promotion. Specifically they are MLH 2015 Hackathon Season codes work till: DEC 31, 2017. So gives a long time to use the credit which is great.
You can use if you have not used a these MLH 2015 Hackathon Season code before. If you were really into buying codes before you likely used this one as there were two popular codes and this was one of them. If not sure you can always create a new account to use.
Have been selling since July 30th 2015, and sold hundreds of codes. Take customer service serious and make every customer happy. You will see my thread is not self moderated that is important to me to show my validity. But not with selling hundreds and for so long am I giving vouches anymore. My history speaks for it's self. Only discounts are given to bulk buyers. If buying 10 or more PM me.
