Example Input: Green Mountain "Nantucket Blend" K-Cups make a very good cup of coffee in my <a href="http://www.amazon.com/gp/product/B000AQPMHA">Keurig B-40 B40 Elite Gourmet Single-Cup Home-Brewing System</a>. This is a very smooth tasting brew that my wife prefers over the <a href="http://www.amazon.com/gp/product/B0029XDZIK">Coffee People, Donut Shop K-Cups for Keurig Brewers (Pack of 50) [Amazon Frustration-Free Packaging</a>] I generally drink in the morning. These are good on both "Small" and "Large" cup settings as well. Highly Recommended! CFH

Example Input: I purchased these little treats as stocking stuffers for our little furry friends. Both Yorkies LOVED these treats. We had to finally buy more since they liked them so much.

Example Input: I picked up a box of this in a discount grocery store in paso robles. The cake was heavenly. I liked it so much, I found another store that sold the mix as well as the icing, and there is even a pink lemonade cookie mix which I bought but haven't tried yet. The taste, is of course lemon, but it reminds me a bit of that flavored mix Country Time I drank as a kid, but less tangy. Its very light and refreshing. I simply loved it. Hope this is more than just a seasonal flavor.
