The number of items will be allocated as evenly as possible so that each student has the same amount. However, this does not apply to dollar amounts. Only item counts are distributed evenly.
Example 1: If you order 6 items and have 3 students on the order, then each student will have 2 items a piece.
Example 2: If you order 1 item and you have 2 students on the order, then only one student gets credit for the item and the other does not.
