However, you cannot use a SuperSaver Stored Value Card if you transfer from bus to light rail. Get a Go-To Card for an easier way to pay your fare. If you pay with cash, drop your money in the farebox next to the driver. Fareboxes accept dollar bills, coins or tokens, but change is not available. On most buses, you pay when you get on. However, on many express buses leaving downtown during afternoon rush hours, you pay as you leave. The same fares are charged for buses and METRO lines and vary by time of day and type of service.
