Here's a bit of free advice: Don't wait until you get to the College to buy your textbooks. If you have your class schedule (I can't remember when in the freshman orientation process you get them), buy everything now. If you don't, I strongly recommend buying everything off of Amazon as soon as you do get them.
(I apologize in advance if you already know this and I'm just being pedantic.) Here's what you do: go to the Current Students tab on the Wooster website and click Bookstore. Go to Books and select your department and course numbers. For each individual course, it'll give you the new and used prices. (Never buy new, of course.) Order those books on Amazon instead and it's a lead-pipe cinch you will save a ton of money. I saved $102.75 this semester alone like this.
Textbooks are basically one enormous scam. It used to be that colleges didn't have to post the class reading lists online before students arrived for school, so they just kept it to themselves. Students arriving at school either had to pay the inflated prices for the books the school had on hand, or order online and miss a week or more of class readings while the books percolated through the mail. It was bad enough that the colleges are now required under federal law to make their textbook lists available a certain time before students arrive, so you can order now and avoid exactly that situation.
Textbook buy-back is a whole 'nother kettle of fish, but suffice to say, it is much better to NOT sell your books back at the end of the semester because there will be a huge glut of textbooks on the market and no one will give you fair value. Instead, wait until the beginning of next semester when everybody's buying.
