Digital textbook code already redeemed
Format: Hardcover
This book arrived unwrapped. Inside the textbook there was a return packing slip from Aug 2024 that someone forgot to remove. Unsurprisingly, upon checking I realized that someone already redeemed the digital textbook code that accompanies the book.
I was sent an opened textbook that someone purchased and stole the digital code before returning.

Buyers Beware! New Doesn't Mean New :/
Format: Hardcover
Buyers beware: despite this being labeled as NEW on the product description, I soon discovered that the e-Book code had already been redeemed. Not only is this incredibly frustrating for academic reasons (i.e., the need to use the e-Book to take mandatory quizzes assigned by my professor), but it is also just so annoying to deal with when the book was already a very costly purchase.

One of the better ones!
Format: Hardcover
As law school text books go, this has definitely been one of the easier to read. I’m hoping that translates to a good grade!

Hilarious Nonfiction!
Format: Hardcover
I'm always on the lookout for a nonfiction book that will grab the students' attention. This is it! The author does a great job of melding accurate information with a fun format. Of course, there's also the narrative tension of not knowing the superpower until the very end, so readers never stop turning the pages. Am excited to see this is a series. Will order the second book today!
