Explanation:

Large scale retailing is where a variety of products are sold in the same physical space. There are some common characteristics that large-scale retailers share: First of all, large areas: generally speaking, the retailers operate in spaces that could be up to 4,000 square meters.
arge distribution signifies a retail structure that is centralized and with a single property that directly manages the various stores, which tend to be scattered throughout a territory with many structures of varying size. In this sense, an example is the Auchan group, a large retailer that operates using different brands (in this specific case Simply, Spaccio Alimentare, Primo Prezzo, etc.).

Conversely, organized distribution is more similar to a consortium model where several individual operators participate. Some examples of this category are Italian companies Crai, Conad, or Sigma.
