For Exclusive Amazon Prime Deals
When you are an Amazon Prime member you get exclusive access to deals on Amazon and through Alexa.
With Prime you get 30 minutes of early access to Lightning Deals, which can often be the difference between getting a deal, and joining a wait list.
You can also use Alexa devices to ask for specific Prime exclusive voice deals, that you can order through Alexa for additional savings and discounts.
This is a small bonus, but it's one that some members will find useful, and it adds to the overall value of Prime for students.
