We discovered kimchi about 3 years ago, thanks in part to The 4 Hour Body (a gimmicky book but some aspects were informative and entertaining nonetheless.) Kimchi is an Asian dish – it’s a spicy, sour fermented cabbage. Fermented foods like yogurt, sauerkraut, real pickles (and kimchi!) are an important part of your diet (have I convinced you read Deep Nutrition yet? Come on people!)
With that, store bought kimchi (or kim chee) seems to fall under one of two categories:
Category 1: Not that good.
Category 2: Not that cheap.
