Ex Input:
I tried this gum after Trident cinnamon became hard to find a couple of years ago.  (Trident told me that they were overhauling the plant that made the gum so it was in short supply but it would be back.)  I quickly discovered that the Flare 5 was far superior to the Trident and I haven't looked back.  It does last a long, long, long, time.  Unfortunatley, as other reviewers noted, it has become very hard to find in stores.  Trident cinnamon is everywhere but now I don't want it.  Amazon saves the day again.

Ex Input:
This tea is a new flavor of black tea by Tazo. It's better than some other brands but not even close to beIng as good as their old flavor of black tea with citrus (which they took off the market). I don't think this tea is worth sending away for because you can buy it locally in most grocery stores.

Hot and Spicy cheeze-its are yummy, but they do have a bit of a funny aftertaste, so you will need a drink.  Also like the other reviewer said, they were smaller packages than advertised.
