Amazon com is launching a new section to its app focused on items that cost $20 or less as the e-commerce leader looks to fend off rising competition from low-cost platforms Temu and Shein. Amazon said the offering, dubbed Amazon Haul, was available to some customers in the U.S. starting Wednesday. Purchases over $3 would be eligible for free returns within 15 days of delivery, a slight difference from its return policy under an Amazon Prime membership.
