About
Costco Gas Prices is an independent data visualization project tracking gas prices at Costco warehouse stations across the United States.
It started with a simple question: how does Costco gas move in relation to the broader U.S. market? I wanted a clearer way to see the geographic spread, price gaps, and timing of changes across the country, so I built one.
More broadly, this fits into the kind of work I like doing: taking messy public information, structuring it, and turning it into something visual and useful. I've written about reverse engineering Life360, mapping Waffle House locations during a hurricane, and visualizing parking ticket data. This is just the latest one.
How it works
Prices are fetched directly from Costco's public-facing warehouse pages on a regular schedule and stored in a database. The map and table reflect the most recently recorded price for each location.
Price history charts show how a station's regular grade price has changed over time.
