This The Great Courses set is in retail-quality condition. The DVDs have never been watched, and the item has gone entirely unused.
I've noticed one under-the-radar flaw in the course guide book: two or three of the corners of the front cover are very slightly creased (See Pictures!). The creases can't be more than one 1/4 of an inch, and they're not readily noticeable.
Please examine the item before purchase, and feel free to reach out with any additional questions/requests!
**ABOUT SHIPPING**
I've selected USPS Media Mail as the shipping service. The upside to this shipping type is its low price, whereas the downside is that the item can take 2-8 business days to arrive. If you would prefer a faster shipping method, the extra fees for which the buyer would be responsible, please let me know.
