It's not about traditional retailing It might seem odd that Home Depot ( HD -0.35% ) is investing in a splashy new distribution center, given that its store footprint isn't expected to grow at all this year. But then again, the Ohio fulfillment center that opened last week isn't about traditional retailing: It's Home Depot's third facility devoted entirely to online order processing. It's also easily the retailer's biggest structural bet on e-commerce. The other two centers, one in Georgia and one in California, weigh in at 1.1 million and 900,000 square feet.
