You can buy a OnePlus 5 (and other OnePlus products) for 10% off if you're a student
Thanks to this new program, if you're a student, you can purchase a brand new OnePlus 5 for $47.90 off if you want the model with 6 GB of RAM and 64 GB of storage space (normally priced at $479), or for $53.90 off if you intend to get the model with 8 GB of RAM and 128 GB of storage space (normally offered for $539). Unfortunately, there's a limit of 1 discounted OnePlus 5 per student, although it looks like there's no limit when it comes to accessories (as long as you're buying everything in a single order).
You'll have to verify that you're a student by logging in to a Student Beans account (or create a new one if needed). More information is available at OnePlus via the two source links below.
