I went to 4 grocery stores looking for this flavor of Jello for my green tomato jam recipe and finally found it here. This jello is wonderful! Evidently it's only carried in the stores during the summer but with harvest time in the Fall, I couldn't find it anywhere in town. This Jello tastes like watermelon and the jam recipe I made with it takes like watermelon jam! Great made as regular Jello too. Yummy!

This tea is ok but it's not nearly as potent as the original product that was available 5-10? Years ago.

Sardines are rising in popularity as people discover more about their health benefits... and that they aren't so stinky after all (especially less so after cooking!).  I've used numerous varieties of the Roland sardines: olive oil, s&b in olive oil, tomato sauce, etc.  The S&B version with low sodium and packed in water is my best recommendation/preference: a great value for the money, and practically a steal when you compare -per ounce- the price with other brands.  Then, consider the discount(s) when purchasing through Amazon, and it'll be tough to choose another.  Why?  Many other brands charge the same price as -or more than Roland- with only a 3.5-oz tin, whereas Roland includes more fish in the tin.  The quality is consistent, and the sardines themselves are quite succulent and versatile enough to be included in stir-fries, salads, pasta dishes, etc. without overpowering the other flavors.  Oddly enough, I was half-mindful when perusing a semi-local dollar store which is renowned for carrying a ton of food items in my city.  I was looking to make some lower-cost and healthier choices in my diet at the time (not expecting to find these, of course, but rather turning my nose up at the usual crud I saw stocked there) when I accidentally stumbled across them.  At $1 per tin, it was a huge buy, so I tried a few.  The rest, as they say, is history as aforementioned.
