Fitbit has expanded its distribution to Macy's, the largest department store operator, according to a report from Piper Jaffray.

The distribution arrangement with Macy's is a “significant catalyst near term” for Fitbit in the fall and holiday shopping seasons, Piper Jaffray analyst Erinn Murphy said in her report, according to Investor's Business Daily..

Fitbit will be in about 650 Macy's stores before the holidays, the analyst said. Her checks indicate that nearly 75 percent of Macy's stores are already selling Fitbit devices. The device is already sold at Kohl's.
