Gas Prices by Brand in This City
Estimated prices based on brand modifiers. Sorted cheapest to most expensive.
Monday and Tuesday are statistically the cheapest days to buy gas in most US cities including Boise. Prices rise Thursday through Sunday as weekend driving demand increases. Filling up Tuesday afternoon before price adjustments is a reliable strategy.
Boise and surrounding cities typically track similar fuel prices given shared supply infrastructure. Differences of 5-15 cents between nearby cities are common depending on local tax differences and competition levels.
A 10-cent savings on 15 gallons equals $1.50. If the cheaper station is 5 miles away and your car gets 25 MPG, the detour costs about 0.4 gallons. Savings above 15 cents per gallon are consistently worth moderate detours.
Most states have price gouging statutes that activate during declared emergencies. Outside of emergency declarations, gas stations set prices based on market conditions. Normal price variation between stations is competition, not gouging.
