About Costco Gas Price DB

Costco Gas Price DB tracks pump prices at Costco gas stations across the United States and Canada. For each station we show today’s price for every fuel grade sold, along with a 30-day price history so you can spot a good day to fill up.

Prices are collected once daily from Costco’s published pump prices. Because collection happens once a day, the prices shown here can lag same-day changes at the pump. US prices are shown in USD per gallon; Canadian prices in cents per litre.

Beyond individual stations, we aggregate prices into city, state/province, and national averages, and rank the cheapest stations in each region — all rebuilt daily from the latest data.

This site is an independent price tracker. It is not affiliated with, endorsed by, or sponsored by Costco Wholesale Corporation. A Costco membership is required to buy fuel at most Costco pumps.
