For the second quarter of 2013 ending Aug. 3, Nordstrom Inc.’s direct sales—which are almost entirely from the web—increased 37% over the same period last year, the retailer reports. In the first quarter of 2013, Nordstrom reported a 25% year-over-year increase in direct sales.

Nordstrom, No. 28 in the Internet Retailer Top 500 Guide, did not give the amount of those direct sales.

In its earnings report, Nordstrom credited the increase in direct sales to “expanded merchandise selection and ongoing technology investments to enhance the online experience.”  Those investments include building out its information technology infrastructure and making it easier for customers to shop online, both through computers and mobile devices.

Total net sales for Nordstrom reached $3.10 billion in the first quarter, up 6.5% from $2.91 billion for the second quarter of 2012, the retailer says. Same-store sales increased 4.2%. Net earnings reached $184 million in the second quarter, up 18% from $156 million last year.

For the first half of 2013, net sales reached $5.76 billion in the first quarter, up 5.7% from $5.45 billion for the first half of 2012, the retailer says. Net earnings reached $329 million in the second quarter, up 7.9% from $305 million last year.

The merchant predicts its total sales will grow between 3% and 4% in 2013.
