I just got an email from Amazon Student. It seems they’re sending out codes for free Android Apps worth 5€ (at least in Germany). I just got two Choice of Games for free with that. If you’ve got an Amazon Student account, check your email, you might have a present waiting for you.
Btw, I’m just posting this because I usually delete those mails unread. It was a happy coincidence that I read this one and I don’t want anyone to miss out on this (or COG on the revenue). I don’t work for Amazon.
