The two friends went on to ace their international trade course, using their knowledge of Feenstra and Taylor's textbook to analyze real-world trade policies and debates. And Alex was grateful that she had made the decision to invest in a legitimate copy of the book, even if it meant spending a bit more money.

As she walked back to her desk, she couldn't help but feel a sense of excitement and relief. She had been stressing about finding this textbook for weeks, and now it seemed like her problem was solved.

As she opened the book and began to read, Alex felt a sense of satisfaction and pride. She was investing in her education and doing things the right way. And as she dived into the world of international trade, she knew that she was well-prepared to succeed.

After some thought, Alex decided to take the high road. She went to the campus bookstore and bought a physical copy of the 5th edition of "International Trade" by Feenstra and Taylor. It was a bit pricey, but she knew it was the right thing to do.
