I ordered a set of twelve books for Sixth Form , 'Book Club ' students at my son's school. When ordering I checked the delivery time, which was stated as being two to four days, which meant that the books would arrive in time for the end of term break. I was surprised and very disappointed to find that in the email confirmation I received soon afterwards, that the delivery time was given as five to ten working days and so the books arrived during the school holiday. I contacted the company but was just told over and over again that the delivery would be on time for the five to ten days! I did note that the company did change the website delivery information to the actual five to ten days it really takes.
