Amazon Prime members can save up to 20 cents per gallon on gas during the promotional period from April 3 to May 29.
Costco operates roughly 550 gas stations across the U.S., giving members plenty of opportunities to take advantage. Gas isn't a small line item for the retailer, either. Costco reports that fuel accounts for about 10 percent of total net sales, a steady revenue stream that helps the company keep prices lower.
