The top 10 neighbors for Costco Gasoline span nine distinct subcategories — not a single other gas station appears among them — making this one of the more category-diverse similarity clusters in the data.
The shape is broad, with no single dominant neighbor pulling far ahead of the rest. Costco leads at 0.99, followed by Costco Optical at 0.95 and Target at 0.91 — both Big Box Retailers or adjacent Costco-branded services. Costco Pharmacy sits at 0.90, and Juice & Smoothies at 0.87. From there, the scores descend gradually through Cold Stone Creamery (0.87), Movies & Theaters (0.87), Nordstrom Rack (0.87), Bakeries, Desserts & Confectioneries (0.87), and Sprouts Farmers Market (0.86).
The subcategory breakdown tells the real story: three of the top 10 are Costco-branded entities (Big Box Retailers, Eyewear, Pharmacies and Drugstores), while the remaining seven span Restaurants & Eateries, Apparel, Grocery, and Entertainment. No other Gas Station subcategory appears in the top 10. The audience for Costco Gasoline looks far more like the broader Costco membership ecosystem — and the suburban errand-runner who frequents dessert shops, smoothie bars, and off-price apparel — than like the audience of any fuel competitor.
This broad, cross-category shape suggests the audience is defined primarily by membership and lifestyle context rather than by fuel-buying behavior alone.
