If you like to buy books online, I don't recall ebay ever putting out leftist crap. Plus, books are often cheaper on ebay as oftentimes you don't have to pay for shipping & handling. If you're a student and use Amazon prime to get books quick, just email professors 2-3 weeks before the semester begins and you should be good. Ask them them which books are absolutely necessary and ask them around how long into the semester they'll be used. Some won't be necessary until halfway through. Also, some stores on ebay have a buy 3 get one free deal that amazon doesn't.
