Ugh, yes. :(
I'm taking 5 classes this semester, 3 credit hours each, for a total of 15. My financial aid has thankfully covered everything thus far, and I haven't needed to take out student loads yet (thank God). The tuition at my school went up again (ughhh), and while my financial aid covers the tuition, I only have ~$300 left over for books.
And my God, books are expensive.
What I've started doing, thanks to my lovely mother's advice, is going to classes the first week to see if it's actually worth getting the books, and the renting the ones I'm able and purchasing the rest I have to. I have discovered the lovely Amazon and their textbook program, and some of the books I need for next semester are rentals for so much cheaper than what my school's bookstore offers, so I intend to do that for the books I need rather than going through the bookstore and purchasing things because good lord are they expensive. :(
tl;dr amazon is going to be great this semester and books are expensive
