The myth of showrooming - the suggestion that tons of shoppers are flooding stores to only use them as a physical showroom as they had always intended to purchase the product at Amazon - lives on. But a survey conducted in late April by Bizrate Insights is helping to add a little clarity. First, showrooming really doesn't happen very often. But more interestingly, when it does, it's more likely to be within the same chain. That's a problem all right, but the name of that problem isn't showrooming. It's internal politics.
