How to save more on gas in Boise
1. Use warehouse clubs
Costco and Sam’s Club typically price 15-25 cents per gallon below nearby stations. Membership pays for itself within a few fill-ups.
2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.
5. Pay cash at split-pricing stations
Stations with cash and credit split pricing typically save an average of 10 cents per gallon when you pay cash.

About gas prices in Idaho
Idaho is part of PADD 4 (Rocky Mountain) and pulls fuel from refineries in Salt Lake City and Billings, with prices that closely track Wyoming and Montana rather than the West Coast. The state gas tax is around 32 cents per gallon. Boise sees the lowest pricing in the state, with Costco, Sam's Club, Stinker Stores, and Maverik competing aggressively. North Idaho (Coeur d'Alene, Sandpoint) typically prices closer to Spokane Washington pricing due to shared distribution networks. Eastern Idaho near the Wyoming and Utah borders sometimes runs 5 to 15 cents below the Treasure Valley because of refinery proximity and lower local taxes.
