Google on Tuesday expanded its shopping home delivery service into the midwestern portion of the United States, coving an additional 25 million people. Google Express shopping service launched two years ago added Illinois, Indiana, Iowa, Michigan, Ohio, and Wisconsin to the roster of states where it will let people order online from selected shops and then get the goods to doorsteps.

"Whether same-day in our seven metro areas or overnight in northern California, it's been a pleasure to see the service become part of people's lives, service general manager Brian Elliott said in a blog post.

Google Express retail partners include Costco, Barnes & Noble, Toys "R" Us, Walgreens, and L'Occitane en Provence.

Google Express members can get free shipping, while non-members are charge delivery fees.
