Although in a metropolitan area of one million, teas such as lapsang souchong are either "out of stock" or have been dropped by cost-cutting managers.
There are a number of companies that sell good tea on line. This one isn't bad. If you aren't familiar with area of production or type, it may take a bit of looking, e. g., find lapsang souchong under black China teas, then click on the black tea box including Russian caravan, and you will find that they have four brands of lapsang. Classic Keemun at $17 a pound is a bargain; not as subtle as the best lapsang, but good. Use one of those little perforated tea balls for bulk tea.
