Q: Although it sounded delicious, I was very disappointed in this coffee. The coffee has a strange, chemical aftertaste ... cup after cup, not just once. Even when it brews, it creates a chemical sort of aroma. In fact, because our single-serve pod coffee brewer was new, I started thinking the problem was the brewer. We assumed it was a left-over manufacturing plastic or metal aftertaste coming through in the water. I even e-mailed the coffee machine maker (Bunn) to see how to remove the aftertaste. Imagine our surprise when a month later we opened a new pack of pods (regular Colombian, not flavored) and were delighted that our machine makes great coffee. When we made a cup of the Senseo Vanilla again -- back came the off-taste and aroma. Perhaps it's the "artificial flavors" used? Be forewarned!

A: Chemical aftertaste - thought it was the coffeemaker, but it was the coffee

Q: No more heavy grocery bags for me -- I've just ordered my first bag of Harmony Farms dog food -- and it was delivered to my door by UPS. The food is excellent quality -- I bought this product based on its healthy ingredients; the dogs love it and I love Amazon for making it so easy to buy! July 2010 - one of my dogs has had bouts of inflammatory bowel disease: previously she had to have special food from my vet (Royal Canaan Duck & Potato for the past 4+years) -- She has tolerated, even thrived on, the Harmony Farms food w/o any problems. Each bag of Harmony Farms is about $20 cheaper than the Royal Canaan. Hard to fight. I am a believer. The canned food is great, too. September 2011 -- my dog who has had inflammatory bowel disease in the past (verified by surgery) has never felt better -- she is a wire and has the energy of a 2 yr old dog (she is 7); she is not on any daily medication. This HEALTHY WEIGHT FORMULA has helped her to thrive. Enough protein, not too much fat seem to do the trick. I highly recommend it.

A: Quality dog food delivered to your door!

Q: This is the favorite green tea in our household. Been using it for years. Was happy to find it here on Amazon, otherwise we had to travel about forty miles to an oriental grocery store to purchase it. Can't even buy any leaf tea of any kind in regular grocery stores any more. By the way "Ban Cha" in Japan simply means common or everyday tea. Not ceremonial.

A:
Good perker-upper
