What Made Home Depot's Huge Stores Pay Off?
Ben Gilbert says bigger Home Depot stores beat Lowe's because extra size and extra products brought far more transactions, and the return on the extra space and inventory rose as the stores got larger.
In 1980, Home Depot stores were twice as large as Lowe's and carried three times as many products. They also had four times as many transactions as the smaller Lowe's stores. Word of mouth, one-stop shopping, and a buying frenzy more than paid for the extra inventory and square footage. The hunch was in place before the first store opened, and it was right. Returns on the investment increased once a store got past a certain product count and a certain square footage.
Home improvement has no cap on what a customer can spend. Purchases can include $100,000 kitchens and home remodels. The same model is what takes Home Depot to a $350 billion market cap.
