Customer satisfaction took a hefty hit in the retail world this year, according to the American Customer Satisfaction Index, and supermarkets were no exception.

Satisfaction with supermarkets dropped 1.3% to a score of 78 in the annual ACSI Retail and Consumer Shipping Report, which was released Tuesday.

Trader Joe's and Wegmans were able to make small strides. In fact, Trader Joe's saw a 1% rise to a score of 86, making it not only the top-ranked supermarket, but the highest rank among all retailers. Wegmans' 1% bump gave it a score of 85.

Whole Foods sank 2% into a tie with Aldi, which remained unchanged at 84. Costco also remained steady at 83, but nearly all other large supermarket chains fell. H-E-B slipped 1% while Sam's Club, Whole Foods, Hy-Vee and Kroger each dropped 2%.

The biggest decrease goes to Southeastern Grocers, which fell 3% to 76. However, Walmart continues to sit at the bottom, dropping another 1% to 72.
