Google is stealthily preparing to launch an Amazon Prime competitor called “Google Shopping Express.” According to one source the service will be $10 cheaper than Amazon Prime at $69 a year and offer same-day delivery from brick-and-mortar stores like Target, Walmart, Walgreens and Safeway (though no specifics were mentioned by our sources). When and if it launches, the product will be a competitor to Amazon Prime, eBay Now, Postmates’ “Get It Now” and even smaller startups like Instacart. We’re hearing that the project is being run by Tom Fallows, an e-commerce product manager at Google, and is an effort to focus Google’s e-commerce initiatives.
