What you need to know: Of the lowest performing chains, this brand pulled no “poor” ratings, but it barely scraped by in 7 other categories, including competitive pricing, checkout speed, produce variety, and local produce quantity. And regarding those produce purchases: Shoppers should know that pre-bagged produce tends to be cheaper by the pound than individually chosen pieces, so weigh that produce for cost savings.
