Amazon is planning to introduce new lines of private-label brands, including perishable foods, by the end of this month or early June. “The new brands with names like Happy Belly, Wickedly Prime and Mama Bear will include nuts, spices, tea, coffee, baby food and vitamins, as well as household items such as diapers and laundry detergents,” reports The Wall Street Journal. “Amazon is ‘carpet-bombing’ the market with new products,” said Bill Bishop, chief architect of consultancy Brick Meets Click. “Private label allows them to test out new prices and distinctive flavors with less risk.”
