Q: For those who love salt and vinegar potato chips, this is the one to choose. The flavor is zippy and tart, with no unpleasant chemical aftertaste like the less "natural" versions of this snack. The 2-ounce bags are just right to share at lunch. The chips are a little greasy, and that's why I've given them 4 stars instead of 5.

Q: This is a great coffee.  Its dark but not bitter, a little chocolaty, and it reminds me of an Adirondack lodge.  I can get them for a better price in a Caribou Coffee store, however.

Q: all of the veterinary products made in China are potentially dangerous to your pet.  Do not buy pet products made in China.
