Walmart Inc. has partnered with Kidbox, a company that uses stylists to create curated boxes of clothing for kids, to launch the Walmart Kidbox stylebox, a clothing subscription service for children. Customers can opt for a seasonal delivery of boxes containing four to five items for $48, about half of the suggested retail price. Customers can go online starting Tuesday to fill out a short style quiz for their children. Items are available in sizes 0 to 14 for girls and 0 to 16 for boys. Walmart shares have gained 10% in 2019 so far while the Dow Jones Industrial Average is up 13.1% for the period.
