I never received the book I ordered. I did e-mail the person I bought the book from three times. They responded to my first e-mail advising me that it may take a couple weeks to get the product. My first e-mail was sent before the final arrival date of the book. My contract with the seller was that the book would arrive by May 26, 2009. The other two e-mails were sent after the May 26, 2009 arrival date, but the seller has not responded. I am starting the 3rd week of my class so I am going to now purchase the book from the school. I had to rate this item with something because my message could not be sent so I rated it as a one, but really cant rate the product because I never got it. Please advise how I go about getting my money back since it was never received. I am assuming it is lost in the mail system somewhere, and if I do receive it, I will return to sender once I get my money back.Thanks for your time.
