Query: Was it the mail service?

I was very disappointed in the service. When I went to pay for this book I was told that if I place my order before a certain hour (on a Monday morning) the book would arrive by that Thursday. Well, the book arrived on a Thursday for sure but it was more than 2 weeks after the order was placed. I was not happy. This is not my usual experience with on-line purchases, but I was counting on this item reaching the address on a timely basis and it did not happen. Can't actually attach a rating, as I am still waiting for it to be forwarded to me.
