i've had stash teas on many occasions (during college, the on-campus outdoor cafe only carried stash teas; one of the places i work now only has stash). also, when left with no option a few times, i bought a pack (chamomile).
there are a few things not to love...the primary two for me are that 1) the flavors leave much to be desired (both in terms of variety and how they taste -- to me, somewhat artificial), and 2) the tea always tastes so...watery! i guess it's just that the herbs/spices in the tea bag aren't strong enough to flavor the water. overall, not a fan.
