I tried this with my purdue.edu email a few days ago and it didn't work at all. I think it was because I used a computer in an on-campus lab to sign up. When emailing Coinbase support I got these responses that, while prompt, were unhelpful in actually fixing the issue:
>My apologies for the trouble! In some cases, we may not be able to credit this promotional bonus to new accounts. If we are able to credit it to your account, it will be displayed on the Transactions page immediately after signup.
>If another user used the same device to redeem the .edu promotional bonus, we unfortunately would not be able to credit it to your account at this time.
