Gas price increase in Vietnam

Yesterday, gas price in vietnam increase 2,100 VND/1 liter. That means now i must pay 22,900 VND/1 liter (A92) and 23,400 VND/ 1 liter (A95) - 1 USD = 22,000 VND.
I often buy 6 liters and ride in 3 days, so bad, too much money spend for gas.

Seller: How many liter do you want?. Buyer: FULL!
