The prestigious honor of being in the #1 spot was previously held by Trader Joe's, however, according to the American Customer Satisfaction Index, Costco (tied with Publix and H-E-B) has knocked Trader Joe's to fourth place.

One of the main reasons for the Costco chain landing in the top spot is that customers feel the wholesaler gives them the best bang for their buck, as reported by CNBC. Other factors that played a role in Costco dethroning Trader Joe's are customers favor many of Costco's friendly features, including the warehouse's layout and merchandise selection.

Massachusetts now has a seventh Costco warehouse as the wholesaler opened a seventh warehouse in Sharon a few days ago. The Sharon Warehouse is located at 160 Old Post Road and is adjacent to I-95 and less than five miles from Gillette Stadium.
