Bollywood actress Shilpa Shetty has blasted stores that are selling masks at "three times" the price when the swine flu situation in many parts of the country is "grave".

"Three days ago I scurried to buy myself a mask wanting to use it at the airport. Imagine my dismay at learning masks were out of stock at the medical stores but are being sold at three times the cost by some unscrupulous stores," Shilpa posted on her blog shilpashettylive.com/blog Friday morning.
