Input: Consider Input: The Good:  Walker shortbread cookies are my favorite, I love them.  I bought the highlanders and each set of cookies came individually wrapped with two cookies each.  If this were the end of it, a five star review.  The Bad:  Unfortunately, Amazon shipped them in a box that was about the same size as the container they came in from the Walkers cookie company.  After UPS was through with the shipment, my cookies were reduced to crumbs.  I contacted Amazon about this problem without ever receiving a response.  Since I bought these "Shipped and Sold by Amazon", I won't be purchasing these cookies from Amazon again.

Input: Consider Input: We wanted the Baconnaise lite after seeing the product on Oprah. We looked forward eagerly to the  prospect of that great bacon taste. The decision in our house was 1 for and 1 not so. The taste is there, the "greasy" taste was also. I won't buy the product again.

Input: Consider Input: I ordered this item because it was on sale and because of the health benefits of green tea.  I wasn't certain how good it was going to be but I was pleasantly surprised.  It tastes refreshing and fruity.  The flavor isn't overpowering or fake.  I mix the powder in a sports bottle along with cold water and splenda.  The powder dissolves easily and the drink has a nice green tea and blueberry taste.  I was so impressed that I have signed up for automatic delivery.  It's a great product.
