“Without a doubt, (Lidl is) putting extra pressure on retail prices,” Gielens said in a call with reporters Wednesday.
The study examined 48 commonly purchased private label products from a variety of categories, including dairy products, meats, produce, canned food and frozen goods. It examined Lidl stores and competitors in six markets in the Carolinas and Virginia.
The study found that supermarkets in proximity to Lidl stores set their grocery prices up to 55 percent cheaper compared with stores in markets without Lidls. (Competing stores were within a 1.7-mile radius of the nearest Lidl, according to the study.)

“The University of North Carolina study validates what we have seen on the ground in every market since launching our stores,” Lidl spokesman Will Harwood said in an email.
As Lidl continues to expand throughout the U.S., other grocers will continue to slash prices, according to the study.
“It is not yet clear who the retail winners will be as the grocery price wars evolve, but there is little doubt that consumers will benefit as retailers are forced to continue dropping prices and offer more convenient shopping services in order to stay competitive,” the study stated.
This summer, the Observer conducted an analysis of the lowest prices of five staple items – a dozen large eggs, a gallon of skim milk, a loaf of white bread, ketchup and 1 pound of lean ground beef – at nine Charlotte grocery stores. We found that Aldi had the cheapest total: $7.69. At Lidl, which expanded here after the analysis, that same list of items was $6.29.

—Kroger lowered prices by an average of 10.1 percent (savings of $22).
—Publix lowered prices by an average of 3.9 percent (savings of $7).
—Walmart lowered prices by an average of 2.5 percent (savings of $3).
