Part of being in Hawaii is shopping at stores like Longs and ABC. I find Walgreens prices to be equal to or greater than Longs, so there is no real price or product advantage.

Most Longs stores are much larger than the average Walgreens

Here is what should worry Hawaiians about Walgreens - their corporate strategy is to place multiple locations in close proximity to each other - like pepperoni on a pizza. They get their customers by being the store of convenience - always around the corner, and always easy to find a late-night or 24hour location.

I am not sure they can damage Longs - but they could turn into a blight on the Hawaiian landscape by building cookie-cutter stores everywhere. In my part of Boca Raton, I have 3 identical Walgreens stores all within 1-2 miles of each other on the same roadway.
