I would disagree with your disagreement :) I consider one of the biggest costs of Walmart to be the time and experience of actually going to Walmart. I generally find the experience unpleasant, or at least a chore, and it is time consuming because Walmarts are so large and then you have to wait in line. I consider Amazon "cheaper" even when their prices are slightly higher because I save time and energy. Now living in NYC, transportation from stores is much less convenient than when I used to live in a city with a car. With Amazon, it just comes straight to my door. Then there is the competition on items. With Walmart, it's all sold by Walmart. Knockoffs aside, Amazon is bringing multiple sellers together where they are competing head to head on prices. That would be like going from Walmart to Target to compare prices on items -- such a time consuming activity that nobody would really do it except for large ticket items.
