I had 5 years between finishing bachelors and starting masters and I was so surprised how much the price of books jumped in that time. The first semester, when my books were over $200 each, I thought well these science books were always a little bit more expensive. But, no every book in ferry class was at least $180. I think my stats book broke $300. I rented it, because I guess that had become a thing. We used to just buy and sell them back. Renting them is probably because they can charge you infinite late return fees if you forget to give it back I imagine. Anyway, I spilled a spit cup full of Copenhagen juices on it, and I was worried they would make me pay for it, but I got away with it.
