Ex Input:
I have ordered numerous teas, potions, lotions and other remedies...BUT have never had a lack of product in an order that was sealed. The tea bag wrapping in question was sealed without a tea bag inside. I would have said something sooner, however...I only tried these when I had a sinus infection and the last 3 times I tried to use one...the sealed pouch was EMPTY. BEWARE!

Ex Output:

Ex Input:
At last- a decaf coffee that doesn't taste decaf! Smooth, rich, flavorful, with no bitter aftertaste. Starbucks worthy (but to my husband who doesn't care for Starbucks, it's way better). We like to drink this in the evening and it's basically dessert with cream and sugar.

Ex Output:

Ex Input:
What can you say about coffee, either you like it or you don't. I liked this coffee, although when I choose to review it I didn't notice it was decaf. That aside, it tastes fine (made in my Keurig) but if you want the kick get the caffeinated one.
