Their numbers have steadily increased from 464 last August to 636 in December and 763 in April. They offer gasoline at prices W40-W90 cheaper per liter (US$1=W1,144) than other stations.

As of last Sunday, drivers could save W88.58 per liter by heading to a self-service gas station, where petrol was selling for W1,892.
