That seems like a decent price for 100 tea bags and it has 800+ reviews with an average rating of 4.6 out of 5 stars.
Plus each bag is foil wrapped. Tastes very different from the typical green tea out there. I use 6 bags in a half gallon jar of water and make a tea overnight. I add a few peeled slices of lemon sometime and keep it in the fridge. The tea is also delicious made hot by the cup. Amazon said I have ordered this 6 times.
