Different retailers are created all with one sole purpose to sell products quite obviousy however what seperates them is the products they sell and the way which they are sold.
Two retailers which are different ends of the spectrum are internet retailers and department stores, this is down to department stores stocking in large numbers with a vast range of products all in one area and are created for convenience, and this is something similar the internet store is created for, it is a means to purchase and order all whilst sat in the comfort of your home on your sofa, so no effort is required and in todays times this is one of the most popular if not the most ways to shop as if you have internet you are able to access so many different shopping platforms, it just a lot easier.
Brands such as ASOS really show internet shopping at its best with multiple brands and varying product range available, where as a higher end department brand such as selfridges or Liberties and contain and even wider range of stock all in one walk around location.
