Thanks to Barry Basden for pointing this out. Everyone knows that. Not everyone cares to get something the cheapest way they can, because they know that You Get What You Pay For. And that doesn't always mean 'expensive is good,' but it does mean that if you care, quality is worth paying for. Same exact product everywhere.
People pay for value.
If an internet company wants to stay afloat and not slash prices to the bone, they ought to be remembering that. W ell, I agree and disagree. It costs a fortune to build a chain of physical stores, to staff it and keep it clean, etc. And imagine the cost of hiring sales clerks who are all polite, knowledgeable and college-trained. And the cost of putting these stores in appealing neighborhoods.
