I don't know if I got a bad batch but this coffee has a nasty plastic flavor. I think the Nantucket Blend is good and the Dark Magic is excellent. My room mate tried it twice and she also thinks the Breakfast Blend is terrible.  Green Mountain makes some very good coffees but in my experience this isn't one of them.

Ex Output:
Negative

This was my first experience of a bad Darjeeling - before, I hadn't known there was such a thing. The first brew yielded a dark rust color tinged with olive-green. The bottom of the cup was invisible. The taste was sharp and astringent. Thinking I'd brewed too long or too strong, I set the first cup aside and tried again. And then again. A light brew of 3 minutes improved the clarity; however, nothing I have tried since has removed a level of astringency and a furred taste that I associate with lesser teas. The wet leaves are the typical size, light brown but unexpectedly interspersed with limp green squares.  The aroma of dry tea in the bag reminds me of old hay - neither moldy nor spoiled, just old. In contrast, the Davidson's Keemun Conjou which arrived in the same shipment smells and tastes like delicious Keemun Conjou and nothing else.  Given the price, I knew I was gamboling and consider this a lost bet. I have given the product two stars instead of one, because I haven't thrown it out (yet). I keep a supply of Lipton's bulk tea for emergencies such as long periods of unemployment, and I don't really need more emergency tea. Perhaps it will work for iced tea.  By no means am I an expert, but I do value tea, and so I hope this opinion helps other buyers who are trying to decide between two Darjeelings. Davidson's ships quickly with value pricing, and so I am not giving up on the merchant. Just on this particular Darjeeling.

I just received my order of 100 count regular bully sticks and am extremely disappointed. "Only ValuePetSupplies bulk Bully Sticks are hand measured for consistent thickness". I beg to differ. The "regular" size is quoted as 9/16" thickness. The product I received is less than 4/16" in thickness. Out of 100 pieces, less than five actually measured up to the regular thickness advertised. My blue heeler dispatched one piece in less than a minute. It usually takes him five minutes.  On the other hand, my toy fox terrier is still working on hers and won't leave leftovers for the big guy to clean up. While I understand that ValuePetSupplies.com sponsors good causes, I will be spending an extra 15 cents per piece and get a much more substantial treat.
