The other major gas distributors are now selling 12kg cooking gas canisters for VND264,500 ($11.89) to VND268,000 ($12.05).
According to gas companies, the price cut followed a fall in the average imported gas price by $67.5 to $300 per tonne in February 2016.
This is the second time gas prices have fallen this year. On January 1, the gas price was reduced by VND31,000 ($1.39) due to a slump in global gas prices.
