Nearly all filling stations in North America advertise their prices on large signs outside the stations.  Some locations have laws requiring such signage.<ref>{{cite news | title = A Shortage at the Pump: Not of Gas, but of 4s | first = Ken | last = Belson | work = The New York Times | url = https://www.nytimes.com/2008/07/15/nyregion/15four.html?_r=1&pagewanted=all&oref=slogin | date = 2008-07-15 | access-date = 2008-07-15 | url-status = live | archive-url = https://web.archive.org/web/20090417103014/http://www.nytimes.com/2008/07/15/nyregion/15four.html?_r=1&pagewanted=all&oref=slogin | archive-date = 2009-04-17 }}</ref>

In Canada and the United States, federal, state or provincial, and local sales taxes are usually included in the price, although tax details are often posted at the pump and some stations may provide details on sales receipts. Gasoline taxes are often [[Ring Fenced|ring-fenced]] (dedicated) to fund transportation projects such as the maintenance of existing roads and the construction of new ones.

Individual filling stations in the United States have little if any control over gasoline prices.{{Citation needed|date=February 2009}} The wholesale price of gasoline is determined according to area by oil companies which supply the gasoline, and their prices are largely determined by the world markets for oil. Individual stations are unlikely to sell gasoline at a loss, and the profit margin—typically between 7 and 11 cents a US gallon (2–3 cents per liter)—that they make from gasoline sales is limited by competitive pressures: a gas station which charges more than others will lose customers to them.  Most stations try to compensate by selling higher-margin food products in their [[convenience stores]].

Even with oil market fluctuations, prices for gasoline in the United States are among the lowest in the industrialized world; this is principally due to lower taxes. While the sales price of gasoline in Europe is more than twice that in the United States, the price excluding taxes is nearly identical in the two areas. Some Canadians and Mexicans in communities close to the US border drive into the United States to purchase cheaper gasoline.

Due to heavy fluctuations in price in the United States, some stations offer their customers the option to buy and store gasoline for future uses, such as the service provided by First Fuel Bank.

In order to save money, some consumers in Canada and the United States inform each other about low and high prices through the use of [[gasoline price website]]s. Such websites allow users to share prices advertised at filling stations with each other by posting them to a central server. Consumers then may check the prices listed in their geographic area in order to select the station with the lowest price available at the time. Some television and radio stations also compile pricing information via viewer and listener reports of pricing or reporter observations and present it as a regular segment of their newscasts, usually before or after traffic reports. These price observations must usually be made by reading the pricing signs outside stations, as many companies do not give their prices by telephone due to competitive concerns. It is a criminal offense to have written or verbal arrangements with competitors, suppliers or customers for:

* Fixing prices and exchanging information on prices or cost (including discounts and rebates),
* Limiting or restraining competition unduly,
* Engaging in misleading or deceptive practices.

Gas stations must never hold discussions with other competitors regarding pricing policies and methods, terms of sale, costs, allocation of markets or boycotts of our petroleum products.<ref>{{cite web|url=http://competitionbureau.gc.ca/eic/site/cb-bc.nsf/eng/home|title=Home|author=Competition Bureau Canada|access-date=10 June 2015|url-status=dead|archive-url=https://web.archive.org/web/20150609000744/http://www.competitionbureau.gc.ca/eic/site/cb-bc.nsf/eng/home|archive-date=9 June 2015}}</ref>
