I was on vacation in Seattle and got a sprained foot. I needed to buy a Chinese rubbing medicated oil for sprains. So looked on Yelp for an Asian store that would sell such medicines and found this place. I was very surprised how expensive it costs. $22.50 plus tax for Wong To Yick 50 ml. I had no choice and paid over $25 after tax. The same bottle sells for $18 on Amazon.
