We were in line to take the Rodoviária do Oeste/Rápida Verde service from Lisbon Campo Grande to Obidos. Several online sites mentioned that you can buy tickets from the driver onboard. And that they take cash, card, debit card or Navigante card.

But when we got to the front of the line, the driver said they only take cash (and we didn’t have a navigente card). Fortunately a kind couple behind us gave us euros and we gave them cash (US dollars). This saved us from having to got to an ATM, get cash and line up for the next bus (which was an hour later - not too bad, TBH).

Hope this helps folks who may be planning to take the bus.
