As students we frequently need books. As film students, we frequently need other accessories for shooting with and don't want to/can't always frequent the cage. For some of those things, owning them becomes a better option than borrowing. For buying, below are two sites that offer useful deals to students.
The first deal is free Amazon Student Prime for a year. Not only is it great for textbooks (and other books), but gear here and there as well: reflectors, memory cards, clamps, etc. To sign up, all you need to do is input school information, and use a .edu e-mail address.
Instead of saving a few bucks to buy something from a third party seller, you spend those few extra bucks to buy it from a "Prime Eligible" seller. What you end up getting is the option for free two-day shipping or $3.99 one-day shipping if you buy your item in the allotted time period. After your first free year, it's $39/year while you're in school after that. After signing up, the top left corner will look like this:
The second deal is the B&H EDU Advantage. A lot of the deals are geared toward teachers, and purchasers for schools, but there will sometimes be open box photography accessories within the student price range. (Useful tidbit: You can pay at B&H using PayPal, so you don't have to enter card information on another website.)
Complete the registration form, and attach a scan of your student ID card, along with a scan, or PDF of your class schedule. In about 24 hours, when you log in to B&H, the top left corner of the page will now look like this:
