Is there ever too much choice

When searching for a product on a website is having a wealth of choice always best?  Websites such as Amazon provide search facilities and filtering options for results but do we really want a shop front for everything that means even the most unique item delivers 3,567 results?  Even including customer reviews only increases this and leads to further procrastination. A tight well selected product selection certainly has some strong selling points. Epic customer experience can more readily be achieved where stock is closely managed in terms of the range of items. Imagine searching through the 3,567 results and then reading and comparing the customer reviews to then find the colour / size is out of stock. Painful and irritating. Promote what you can sell and make it smarter and faster for customers to find products. Product segmentation with specific "stores" makes shopping simpler.
