The country's 72 largest grocery chains have just been ranked by customer data science company dunnhumby, and it seems a store only available in 10 states has come out on top

A Southern grocery chain has been named best in the United States for the fourth time and many were shocked to find out it wasn't Walmart or Costco.

H-E-B was among several regional grocery retailers that dominated the top spots in Dunnhumby’s annual ranking.

A gallon of Walmart’s Great Value 1% milk is $3.88, down from $3.93 as last month. A gallon of Haggen’s Value Corner 1% milk is $3.99, the same price as last month. A gallon of WinCo Foods’ 1% milk is $3.19, the same price as last month.

A nationwide study named San Antonio-based H-E-B as the top U.S. grocery retailer for the fourth time in eight years.

The price of eggs has skyrocketed -- if eggs are even available -- at some Reno grocers as avian flu continues to cause nationwide shortages. The shelves have been empty for nearly three weeks at the Safeway at Damonte Ranch Town Center, according to employee Avi Weiss.

Shelves at the Walmart in Hayden were wiped out entirely Friday as supply chains grapple with a nationwide avian influenza outbreak.

A new tool developed by researchers at Mass General Brigham is aiming to change the way consumers and policymakers think about ultra-processed food.

The analysis evaluated the 72 largest retailers and comprised intel from 11,000 U.S. consumers surveyed.
