How Costco keeps gas prices low
Costco treats fuel as a membership perk, not a profit centre. By buying in bulk and running high-volume stations on slim margins, it can post a Costco gas price that sits below most nearby stations. Because members are already driving to the warehouse, cheap gas keeps foot traffic — and membership renewals — high, so the savings are built into the business model rather than a temporary promotion.
In Canada you need a valid Costco membership to fuel up, and the pump reads your card before dispensing. The trade-off is simple: you pay an annual membership fee, and in return you get a Costco gas price that can save regular drivers well over that fee each year, plus the same top-tier detergent gasoline sold at major brands.
How we track Costco gas prices?
We check Costco gas prices daily and refresh regular, premium, and diesel for every Canadian warehouse, alongside a 30-day trend so you can see which way prices are heading. Numbers are gathered from publicly available sources and are meant as a guide — the price posted at the pump is always the price you pay.
