Amazon’s One-Day Shipping Is a Perk Few Retailers Can Match

Amazon.com Inc. shook investors and the retail industry last week, shortly after announcing its first quarter earnings report. “So, we’re currently working on evolving our Prime free two-day shipping program to be a free one-day shipping program,” Brian Olsavsky, the chief financial officer, said almost nonchalantly a few minutes into his regular conference call with analysts.

The move eclipsed both the day’s good news (a larger than expected quarterly profit) and the bad (dramatically slowing sales growth). It set Wall Street’s Amazon watchers into a mad scramble to calculate the impact of the projected $800 million it will take over the next few months alone to achieve the accelerated shipping feat.
