Thanks to all customers, codes have been restocked.

To answer a few questions:
Can these stack? As mentioned multiple times these are all the MLH 2015 Hackathon Season event.   You cannot stack same event, this is why so many people have multiple accounts.
Will I sell accounts? No I do not sell accounts just codes.  This is in part to try to stay within amazon rules.
How long does it take to get code from payivy? It is very quick but it does wait on a confirmation so it can not be cheated by double spend.  But the store is open 24x7 and sends codes quickly after it verify payment.  It is much quicker then any human could do with being open 24x7.

If any questions feel free to PM any questions I am always happy to answer them.
