PROBLEM: Loose prickly pear tea makes a great iced tea but it is very difficult to find in pure form.  This tea is black tea with prickly pear "flavor". The shipping cost is twice the cost of the tea.  If there is a prickly pear component it is all but undetectable when I drink it. It just tastes like regular black tea.  Very disappointing.
