Did you order something on our website, but it hasn't been assigned yet? This means we currently do not have enough stock to supply your demand. The assigning order follows the principle 'first come, first serve'. Do not worry however, as we order new books on a weekly basis. This is typically sundag evening. The delivery time for course material is generally between one and two weeks, except for the very beginning of the semester (then it is typically a little bit longer, since our supplier has the most work in this period). Foreign textbooks may take longer to arrive with us, but this is not necessarily the case. Note that the waiting time can be slighly longer when you order something after we just placed a new order with our supplier (so when you order something on monday, we will place your order coming sunday, this makes it look like you have to wait a week longer). Our advice is to order everything you need as soon as possible in order to avoid long waiting periods.
