I order two times from this website, the first one arrived 2 weeks late, the second one never arrived. The placed the second order on March 17 that was supposed to arrive on April 3, it did not, I contact them, then they told me the 9th, I did not, they keep changing the date. When I said I wanted my money back, they told me that I have to wait 8 days from April 10 (the last day they said the book was going to arrive to ask for a refund). So, they will keep changing the dates so you never get your money back. Think a lot before using this service, is cheap? Well, when you paid for something you need now and arrive (if it arrives) after you finish the class, do you think it was cheap?
