I shopped at Walmart in the Midwest and on the East Coast. Here are 7 surprising differences I noticed.

• I visited Walmart in Wisconsin and New Jersey to compare stores in the Midwest and the East Coast.
• Milk was less expensive in Wisconsin, but a dozen eggs cost the same at both locations.
• New Jersey’s Walmart had a food hall startup, Wonder, founded by a former Walmart executive.

As a Midwesterner who moved to New York City a decade ago, I still find myself surprised by regional differences in national brands.

As part of an ongoing series comparing nationwide retailers in the Midwest and on the East Coast, I visited Walmart locations in Wisconsin and New Jersey to compare their prices, offerings, and store amenities.

First, I visited a 200,000-square-foot Walmart store in Manitowoc, Wisconsin.

The following week, I visited a Walmart in Teterboro, New Jersey, around 8 miles from Manhattan. Unions and politicians have long blocked Walmart stores from opening in New York City due to concerns about its potential impact on local businesses.

The 150,000-square-foot Teterboro store is one of 12 flagship Walmart stores in the country, offering technologies and amenities unavailable in all locations.
