Hi @Liker_Boon,
I have recieved the coupon code from the github developer package but whenever I apply the coupon it gives out an error " The coupon is either applied before start date or after end date."
Thank you
Same here. Got any way to fix it?
Hi and welcome to the forums!
It sounds like your code might be expired. When were you given the code?
I received it yesterday on github
I have the same issue as the above 3 students!

I just followed-up with you via DM 
Hi,
The same thing happened to me I also received a coupon code from the GitHub Developer package but the code is already in use, “which means the coupon code was already expired”
Hi there and welcome to the forums! I’ve reached out to you via DM to try to troubleshoot.
Did you apply your Atlas credit code to a MongoDB instance? Are you trying to apply the credit code to a different MongoDB instance? If so, please be aware that you cannot transfer free credits between MongoDB instances. Once you’ve applied the credit code, you can only use those free credits in the MongoDB instance you applied them to.
If you’re having issues with your Atlas code and reply to this thread, please be aware that the MongoDB offices will be closed for the holidays from December 23rd to December 27th. Expect a response on or after the 27th. Happy Holidays! 
Same Problems here.
please help
