Consumer Reports has released its latest supermarket report, which ranks America's best and worst grocery stores. The findings are based on a survey of more than 62,000 Consumer Reports subscribers. Wegmans claimed the top spot in the new report. Other popular chains, including Trader Joe's and Publix, didn't fall too far behind. Here's a look at the full rankings from worst to best, according to reader scores. Consumer Reports said a score of 100 would mean customers were completely satisfied with their experience.
