Jacob Passy, writing at MarketWatch, explains that the Internet is taking what was once difficult—finding the best price—and making it easy.

As more shoppers move online, the competition they are fueling between e-retailers like Amazon AMZN, -0.50% and traditional retailers like WalmartWMT, -0.08% and Target TGT, +0.16% is causing prices to become more uniform, according a new working paper distributed this week by the National Bureau of Economic Research.

When examining the price of grocery products at Walmart, Cavallo discovered products were more likely to have smaller differences in price across locations if those products could also be purchased on Amazon.
