Can you post a screenshot with event name please?
I haven't redeem them to my aws account but I assure you these are from different event which other legit sellers ( leonsnow , kingda, Blackshadow007) have listed on their thread. So these will not conflict with other coupons you already redeemed. I can send the coupon first if you want and after assurance you can send the money.
Yes True. its a new event. but officially, AWS stopped issuing edu codes with effect from December 7, 2019.
