The best online shopping sites of 2025, according to customers—and no, #1 is not Amazon

Stacker ranked 23 major online retailers using data from the American Customer Satisfaction Index. Stores are ranked by 2025 customer satisfaction, and ties were broken by the higher percent change in customer satisfaction over the last year, with any further ties remaining. The retailers included are the ones for which the ACSI received enough responses to rank customers' opinions.
