Amazon’s Music Unlimited streaming music service is normally $7.99 per month if you’re a Prime member or $9.99 for everyone else. Students now automatically receive a hefty discount that lowers the cost of the service to just $4.99 per month. That price does not require Prime membership. If the student is a Prime Student member, which is free for 6 months and $49.99 annually after, their first half a year of Music Unlimited is just $6. To qualify for the student price of either Music unlimited or Prime members, you must have a .edu email account.
