This is pretty good regular style soy sauce.  But it is not super-wonderful-better than any other good quality soy sauce you can buy in an Asian market.  The main value is as a unique gift.   In the Japanese soy sauce world, there are 4 types: regular, mild (usukuchi), for raw fish (sashimi) and light colored.  Bluegrass soy sauce is regular style.  Compared to Kikoman (a good commercial brand that is widely available) Bluegrass starts saltier, is flat in the middle, then ends with a complex & interesting flavor.  Kikoman is less salty initially and has a round, full flavor in the middle.  Doesn't have the complex ending flavors.  For me, the initial saltiness of Bluegrass is a minus and Kikoman's full middle flavor is a plus.  I prefere Kikoman, especially for dipping sushi where the flavor is more direct.  But I lived in Japan for many years and am used to the standard Japanese flavor.  I haven't tried Bluegrass blended in other food as a background flavor, which is how soy sauce is usually used.   Bluegrass is a perfectly good soy sauce.  Each brand has a different flavor and everyone has their favorite.  If you want a unique Kentucky gift for an Asian friend, this is different than the standard bottle of Bourbon or box of chocolate.

These are good sunflower seeds at a good price if you prefer the unsalted variety, which can be hard to find.  One thing to keep in mind though, is the expiration or "best by" date.  For example, if you order these in April and the batch you receive has a June "use by" date, it may be a stretch to consume the 300 bags before the seeds start going rancid on you.  Since they're roasted in oil and unsalted, these seeds may spoil more readily than the salted variety, even if refrigerated upon receipt.  Amazon doesn't seem to specify "use by" dates for the food products they sell, so it's a gamble for the purchaser.  I'm assuming that Amazon won't ship stuff that has "expired", but they probably ship out the oldest stock first, and the "use by" date on the item may not be what you would select if you had a choice.
