Delivery wars: Putting same-day service to the test

Same-day delivery is the latest battleground between retailers fighting to compete with Amazon's swelling influence.

The online behemoth has altered consumer behavior, with shoppers across the country increasingly expecting quick and cheap shipping for goods. So what's a competitor to do, but try to one-up the mega-online superstore?

Google Shopping Express launched in Los Angeles and Manhattan on Monday, allowing consumers to shop for a select number of items from eight retailers and have them delivered by Google the same day. The pilot program in Manhattan currently includes TargetCostcoWalgreens,FairwayStaples, Toys R Us and Babies R Us, and L'Occitane en Provence.

But does same-day delivery live up to the hype? CNBC's Courtney Reagan shares her experience.
