I was trying to make a purchase after searching everywhere for this textbook and my transaction would not go through. As I was trying to figure out what on earth was going on, my husband then called to let me know that our bank had flagged it as suspicious and blocked the transaction. Thank goodness because I started searching for reviews of the website and came across all of these horrible reviews. I did not re-attempt the transaction after talking to my bank for these reasons, so I can't say anything about their customer service or anything else... but if my bank is telling me to stay away... I'll listen. I thought some might find this valuable/helpful information, hence the review despite no purchase.
