Example Input: Ghirardelli isn't the finest chocolate you can buy, but it's pretty good, and the Intense Dark Assortment is both inexpensive, and provides you a few possibilities.  I've lately taken to unwrapping a 60%, 72% and 86% cacao square for each dinner guest and setting them on an individual saucer, to serve as an after-dinner sampler with red wine or Scotch. That's been a pretty popular approach. A similar approach also works "therapeutically"---if someone's having a bad day, sitting them down with a small assortment of increasingly intense chocolate isn't a bad path to feeling a little better.  I do wish that there were the same number of each in the bag; that's the only downside. Of course, if you really want the sets of three to serve to guests, you'll have to go through the tiresome task of somehow eating the extras. Darn.

Example Input: I'm presently on a diet and I was at my Fresh and Easy Neighborhood Grocery looking over possible diet foods. I wanted things that were tasty, non-fat and low in calories. I came home with about a dozen items. That's how I discovered the Tillen Farms Pickled Crispy Asparagus. Well, I've always liked asparagus anyway and I've enjoyed several brands of pickled asparagus. This Tillen Farms brand is really, really good! It's the best I can recall. There's an excellent flavor and a big clove of garlic down in  the bottom of the jar which I'm looking forward to eating. I can't believe how good this asparagus tastes and right on the front it says "only 60 calories per jar!" Now this is my idea of a good diet food!  Gary Peterson

Example Input: Only one store in my area, Sprouts, sells wheatgrass in their produce section. Whole Foods sells it, but it is a goodly distance from my house so I only get wheatgrass from them once in a great while. I have a bunny who enjoys wheatgrass as a treat, so I go to Sprouts to get it for her, but wanted to grow my own since it is expensive and requires frequent shopping trips. So I bought these kits and decided to grow it myself. First I have to say I was impressed at how quickly they shipped my order. So I planted the seeds on Friday and by Sunday night, I had wheatgrass sprouts like crazy. The instructions are clear and easy to follow, and deliver abundant grass as promised.  I have to say, though, that the grass doesn't look at all like the wheatgrass in stores. The blades are way taller (8 inches) and about twice the thickness of the wheatgrass I am used to buying for my bunny. I took pictures but discovered that my camera's memory card doesn't fit this new computer, so I can't show prospective buyers a picture of it. Rats. Since bunnies have sensitive digestive systems and you have to be careful what you feed them, I don't feel safe feeding this grass to her. I can't return it because I aready cracked open the kit and grew grass from one of the three seed kits. The grass is probably fne, but as a bunny owner, I want other bunny owners to know that this grass isn't like the wheatgrass in stores, jut so they aren't surprised and disappointed like I was.
