Where to get my textbooks

I can't afford the ridiculous prices of new textbooks for my engineering curriculum this term. My school insists on using the newest edition of books, so I can't even find used copies.

Where can I get the books for cheap or free? Can't ship, don't have enough time.

You are fucked.

Build a printing press.

buy them, go to copy place, copy them, return book. Some places will even do it for you.
