Macy’s Inc. said Tuesday it expects to add about 725 new positions over the next two years as it looks to expand its website offerings.

Shoppers have been increasingly moving their business online, and Macy’s, for its part, has seen its online sales grow in the double digits on a percentage basis over the past few years. For the first 10 months of fiscal 2010, online sales were up 29 percent.

Macy’s, which has about 161,000 employees, expects to add the positions in New York and San Francisco to expand macys.com and bloomingdales.com.
