[Q]: This tea is stale. I have had this brand and kind of tea many times, so I know how it should taste. It's dated Jan. 2013, but it must have been stored improperly. It has no fragrance and no taste. Even the teabag paper looks yellowed. It is worse than supermarket tea. I cherish my breakfast tea, so am very disappointed, especially having bought six boxes of this useless stuff. I tried to give it no stars, but that's not allowed, so I gave one for prompt shipping.
[A]: Negative

[Q]: I have tried various brands of stevia, but I always come back to NuNaturals. I buy the 12 ounce container because I use it to sweeten everything. If you have a sweet tooth as I do but don't need the added pounds, then this is the ticket for you. I drink a lot of tea, and this is my sweetener. A lot of other stevia brands leave a bitter after taste, but this is the best that I have found to resolve that problem. Highly recommended.
[A]: Positive

[Q]: If you are going to eat potatoes, go organic and the real thing...not in a can. Big mistake. I like some canned foods but potatoes are a few miles away where you can get the real thing, cheap.
[A]:
Negative
