This question already has an answer here:
I've recently enrolled in an Introduction to Computer Science II course in which the professor allowed me to skip the prerequisites.The problem is, I don't have the textbook from the previous course, Java How to Program 10th Edition Late Objects - Deitel & Deitel. The course and the one before it both encompass the same book, so I would like to catch up before the course starts.
While browsing on online stores, this led me to two different books, the 'Global Edition', and the US edition. Seeing that the Global Edition was half the price of the US version and I was on a budget, I thought it was a steal. There are many choices online with international editions at around $60 and the US at $150.
Why would the global textbook be lower than half the price than the US edition? What's the difference? I've read around that there is not much of a difference except for the cover, but why would that call for such a lowered price? The US book comes with access codes and other features, will the Global also come with those exact features?
