They are generally, if not always, a really bad idea. Right now physical retailers are rightfully shaking in their boots as they continue to lose money and attention to e-commerce businesses. Amazon gets the most attention since they are so agressive with their customer offerings, things like same day shipping.
Physical retailers are trying to play Amazon’s game and it is not driven by competitive competition, but desperation and fear. Why cut in to your thinning profits in the hopes that things will change in your favor? It is a thoughtless way to run an organization, but people construe such decisions into being thoughtful with such logic as “we benefit from all their research and hard work!” or “it will bring us more business!”.
Companies like Best Buy really need to look at why they are on the path to extinct-dome. And it is not because they are Amazon’s showroom or have physical locations to pay for.
