I'm interested in purchasing a used copy of 'The Great Gatsby' from ThriftBooks. Please search for the book, identify the different conditions available (e.g., 'Good', 'Acceptable'), and explain what each condition means according to ThriftBooks' grading system. Also, confirm the general free shipping threshold for US orders.
Navigate to thriftbooks.com. Use the search bar to search for 'The Great Gatsby'. Click on a search result for 'The Great Gatsby' to go to its product page. Locate and identify the different condition options available for the used copies of the book. Click on any link or information icon related to 'Book Conditions' or 'Condition Definitions' to understand ThriftBooks' grading system. Explain the meaning of at least two different book conditions (e.g., 'Good', 'Acceptable') based on the website's description.

The agent successfully navigates to the product page for 'The Great Gatsby'. The agent identifies at least two different book conditions (e.g., 'Good', 'Very Good', 'Acceptable'). The agent provides a description of what at least two book conditions mean according to ThriftBooks' standards (e.g., 'Good' means 'a used book that may have some wear but is still in very readable condition', 'Acceptable' means 'a readable copy but may have significant wear and tear'). The agent states that the general free standard shipping threshold for US orders is '$15'.
