Changes in sales velocity need to be accounted for by retail supply chain managers in order to be able to fulfill shopper demand and prevent stockouts. While seasonality effects throughout the year and weeks (e.g. summer holiday sales dip, weekend sales peak) are generally known, little evidence exists on intraday purchasing patterns.
