Rebelbooks was definitely my choice over the UNLV bookstore and Beat the Bookstore. You ask why, because they had the correct selection that corresponded to your classes and the cheapest. They also give you more money for your buy backsl. I was definitely a regular here if I didn't buy my books from half.com. My suggestion for students is to look around online and at the bookstores and see which options bet suits you whether you need to rent or buy. Renting here is definitely the most inexpensive option, but some books you may need to keep for future reference. The staff are pleasant and about every time I come someone approaches me if I need help locating my book. Aside from the books I also come here for my rebel gear. A lot cheaper than the UNLV bookstore again, but I don't know if all of it is exactly the legit registered "NCAA" crap, which may be the reason why for the lower prices. They also have UNLV memorabilia, I am slowly buying this stuff for my office at work. It is nice to have, so you could rep your Alma mater which sort of got you the job or career of your dreams.
They used to have a loyalty program for every $100 you spend, you would earn $10 back in store credit. The was easily done considering the prices of books, but unfortunately they discontinued it.. Bummer!
