Not the parent poster, but a distribution centre for stores has a different function to a distribution centre for individual customers. The former is about getting whole boxes of products onto large trucks to deliver to stores, the latter is about getting individual items from inside those boxes into bags in vans for individual customers. For that you need a different warehouse layout and many large businesses won't have that space available for the scale they need.
