Walmart is looking to branch out with clothing. The retail giant is debuting four private label brands to be available in Walmart stores and online starting March 1. Items are expected to be priced between $5 and $30. The move is part of Walmart's push into the apparel space. It's also trying to one-up main rival Amazon, which has successfully won over fashion brands, scoring deals with Nike, Calvin Klein, Kate Spade and Levi Strauss.
