Today I've monitored online gas stations in internet where is possible to buy gasoline for money, not for special coupons. It is possible to do with gas stations of the "Olas" network. I've called to our town gas station and asked is it possible to refuel the car? They replied that they don't have gasoline now, but it might be available on Saturday, in the afternoon.

The price is shown as zero. It is means there is no gasoline at the station, but line of cars is very long.
