Google same-day delivery expands to Manhattan, West LA

Until now, Google Shopping Express was available only in the San Francisco area -- but it has to keep pace with Amazon.

Same-day delivery has become a new battleground for two of the Web's biggest companies.

Google has expanded its same-day delivery offering, called Google Shopping Express, to Manhattan and West Los Angeles, the company announced Monday. The service is already available in the San Francisco Bay Area.

Google Shopping Express takes a unique tack on online shopping. The company has partnered with both major and local retailers and allows customers to peruse their inventories from the site. Upon placing an order, customers choose a delivery window for that day. The idea is to combine online and local shopping and to expand Web-based revenue for local firms.

Monday's announcement is clearly a shot over Amazon's bow. All last week, Amazon was in the news over its expansion of same-day delivery service in several cities. The timing of Google's announcement suggests the search company doesn't want people to forget about its own service.

Speaking of timing, and convenience: On Monday, Amazon unveiled a partnership with Twitter that lets people reply to a product-related tweet with the hashtag #AmazonCart to get that product added to their Amazon shopping cart.

As for same-day delivery, Amazon's chief concern at this point is reducing its reliance upon FedEx, UPS, and the US Postal Service, which all take a bite out of margins. The company is testing drone technology and other ways to get products to customers. Google, on the other hand, operates its own Shopping Express delivery service, sidestepping traditional providers. That, however, means the rollouts to other cities might take longer.

Google is offering to chip in $10 to those who place a first order on Monday. The company is also offering free six-month delivery in all cities as it works on a long-term pricing plan.
