Amazon.com Inc.($AMZN) is expanding its new local deals site to New York and other parts of the country, hoping discount-happy consumers will flock to its offerings as they have embraced market leader Groupon.

With the additions, AmazonLocal will be operating in 30 locations in 10 states, all within about three months of the service's initial launch in Boise, Idaho, in early June. Although it's still small compared with the market leaders, Groupon and LivingSocial, it shows that Amazon is keen to leverage its popularity as an online retailer to compete in this nascent yet fast-growing market. Amazon also has an investment in LivingSocial.
