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.

This tea is not so tasty in my opinion. But one thing about opinions is that every one has one and we do not always agree.

We are always pleased with Amazon's packaging. Chips are never crushed or broken, always fresh. We really liked this brand/flavor of chips. Very tasty!
