I go grocery shopping every Sunday afternoon. It’s therapeutic and just plain necessary. I’ve taken a liking to Harris Teeter in Navy Yard and at this point, I know the store like the back of my hand. I know that produce is on the far right end of the store and eggs, milk, and butter are on the far left. I know that a 12-pack of Schweppes ginger ale will likely be buy-one, get-one free. And I’m still confused as to why I have to put my cart on the opposite side of the register during checkout. But I do it anyway.

Now, thanks to non-profit Consumers’ Checkbook, I know how my Sunday ritual stacks up against that of locals who prefer competing grocers.

In the latest issue of the non-profit’s magazine, there’s a detailed analysis of local supermarkets that compares prices using “an apples-to-apples market basket” of 152 items. It also shows data on varying aspects of stores’ quality, which was collected by surveying shoppers.

Wegmans fared well in both categories. In terms of pricing, Wegmans is 11 percent lower than average prices at Safeway. Plus, 94 percent of customers rated it superior overall—landing the Rochester, NY-based chain at number one for quality.

Giant’s pricing is seven percent lower than Safeway. With these stores’ pricing labeled “average,” Walmart, Food Lion, and Super Target had the lowest price points of the bunch. Whole Foods Market and Chevy Chase Supermarket require customers to spend the most at 34 percent higher than Safeway and Giant’s averages.

This data was first reported by WTOP.

In terms of quality, Food Lion, Giant, Safeway, Shoppers Food Warehouse, Target, and Walmart need a clean sweep—not one of them scores 40 percent or more in the superior overall category. Walmart scrapes the bottom at 26 percent.

While Whole Foods Market is pricier than average, they make up for it in quality, as 77 percent of customers ranked it overall superior. Likewise, Harris Teeter—which was only three percent lower than Safeway’s averages—scored the chain superior in overall quality at 73 percent.

Regionally, Target and Walmart stores that are based in D.C. have higher prices than their suburban counterparts—at five percent and six percent, respectively.

The data also tells how much can be saved at warehouse stores like Costco and BJ’s and alternatives to grocery stores like Aldi’s and Trader Joe’s. Plus there are plenty of tips on saving wherever you shop.

DCist readers can access the full report until next Tuesday.
