Department store chains Macy’s and Bloomingdale’s are challenging Amazon by expanding same-day delivery service to nine additional markets.

The expansion increases the company’s same-day delivery markets count to 17, including eight same-day delivery markets piloted last year.

Starting this month, the retailers same-day delivery services will be available in Atlanta, Boston, Dallas, Honolulu, Las Vegas, Miami/Ft. Lauderdale, New York City/Western Long Island, Orange County, California and Philadelphia.

The customers can avail these services for products purchased online for a flat $5 above standard ground shipping fees.

The same-day deliveries are powered by Deliv, a crowdsourced delivery provider, in collaboration with major mall owners, including General Growth Properties, Macerich, PREIT, Simon Property Group, Taubman Centers and Westfield.

Macy’s chief omnichannel officer R.B. Harrison said: "When we piloted same-day delivery in eight markets initially last fall, we learned that our customers appreciate the additional option of having their purchase brought to their home or office in a matter of hours. It is an important part of our value proposition as an omnichannel retailer serving customers who shop our stores and websites whenever, wherever and however they prefer.

"Our ability to expand same-day delivery is rooted in local merchandise inventories at Macy’s stores, as well as a newly expanded delivery footprint of our partners at Deliv."

Customers can return the products they bought by authorizing the return online and scheduling a pickup time at their home or office.
