[EX Q]: I love Twinings Lady Grey but the most recent batch was pretty bad. Regardless of how I brew it I get an odd odor that masks the characteristic Lady Grey aroma. I used some older tea under exactly the same conditions and got a perfect cup. I've got 6 tins of this stuff and it is a lost cause.
[EX A]: Negative

[EX Q]: these are grossly overpriced. It is a package of three boxes but when you take into account that they are a dollar of two per box than they should be, you then have to pay for shipping. Sorry, I would skip them. My local grocery store carries them and a box is anywhere from 2.98 to 3.49 each. Although these are healthier than some other cookies, you still have to watch the fat, sugar and salt contents. Whole foods are much better for you but in a moment or two of indulging, these fit the bill. Just the price on this site is ridiculous! Ask your grocer to start carrying them.
[EX A]: Positive

[EX Q]: This is a GREAT waffle mix! I have allergies to preservatives and to find food in general that is great tasting without the preservatives is a huge challenge. I have tried several other mixes and this one is by far the best. I totally don't understand the reviews about the bad taste and "all the chemicals"--read labels of other mixes and you will see this one is not full of all those ingredients. There are certain kinds of ingredients that these mixes need, such as levening, and when you use REAL butter, NOT the "tub" butter that contains water and other nasty stuff, these are THE BEST WAFFLES EVER!
[EX A]:
Positive
