I have shopped with Nife is Life a few times now.
I am Italian and most of their products are good and those you would find in Italy.
However, some products are bad quality, for example Borgo Fiorito lentils, I was expecting to get good quality Italian lentils produced in Italy. Instead I found that Borgo Fiorito lentils are product of the USA and only packed in Italy (funnily enough in a non lentil producing area ie. Salerno. Another bad quality product is the mixed candied fruit, canditi misti, I would expect to find candied citron, which is the product Italians typically use.
Check the products and their origin carefully.
