In this Tuesday, March 5, 2013, photo, shoppers push their carts at the Costco store in Nashua, N.H. Costco's fiscal second-quarter net income climbed 39 percent as it pulled in more money from membership fees, sales improved and it recorded a large tax benefit. The wholesale club operator earned $547 million, or $1.24 per share, for the period ended Feb. 17. That compares with $394 million, or 90 cents per share, a year earlier. (AP Photo/Charles Krupa)
