Trader Joe’s has been dethroned as America’s favorite grocery store. The 2016 favorite was knocked from the top spot by both Publix and Wegmans in a new study by consumer experience management company Market Force. Publix and Wegmans tied for first in the annual study, which looked at over 12,000 shoppers to determine which chain customers love the most. Both chains scored 77 percent on Market Force’s Customer Loyalty Index, narrowly beating out Trader Joe’s, which scored a 76 percent. But Trader Joe’s did rank first in one category -- the most courteous cashiers. Take a look below at the 20 grocery chains American shoppers claim to be their favorite, according to the study.
