Staples is making it easier for its customers to follow Wall Street. In an announcement today by the Wall Street Journal Interactive Edition, subscriptions to the online publication will go on sale in the office retailers' 200 outlets across the country. Beginning this week, Staples customers can purchase 60-day subscriptions for $4.95 or a 13-month subscription for $49.00 through computer terminals at the front of each store. The Wall Street Journal aims to draw readership from Staples' largely small-business and home office professionals. Terms of the deal were not disclosed.
