We had to buy a copy of the AACR2, which was quite expensive since they update it every year so you can't really get an old one. My prof. didn't make my class get Sears, but they had a rental program at our book store because it crazy expensive.
We had actual books we had to buy, as well as articles to read in the library. I think I probably spent about 300 a semester. I sold them to others on my course, so I got most of my money back.
Less than I spent in undergrad, but that was in the States.
