I would just as soon see the store differentiate themselves from each other. Few things are more depressing than finding the exact same selection is multiple stores.
When my brother retired from the USAF, and we went tool shopping, I was stunned to see just how few of my tools were available from the 'public' vendors. Even among 'premium' brands carried by the box stores, the exact tool models were often absent.
The lesson here is that there is still a major role played by the supply houses and 'professional' tool suppliers. You know - the sort of tool store that opens at 6AM during the week, is closed on weekends, and is located in the dark heart of the industrial area (and lacking any fancy signage too!).
