What if a retail store offered great advice and let you order online so you get the best Internet price?
One reason why I almost never visit a retail store anymore is because the best deal is always online.
So rather than take it as a challenge for retail, embrace it. Can one build a retail business that relies on ordering stuff from the cheapest online retailers?
I can think of the obvious reasons why not. But if you think creatively, wouldn't that make sense? Even the cheapest online retailers offer some kind of referral compensation. There may be other ways to make money than making a profit on the big ticket item that your visitor came in to order...
