Walmart is the most popular store in America. More than half of all shoppers in the country visit a Walmart location in a given month. Apart from the discount store, only McDonald’s can claim a majority of Americans as customers.

24/7 Wall St. reviewed foot traffic figures at major U.S. stores provided by data service company Placed Insights. According to Placed Insights, which monitors on a monthly basis hundreds of thousands of American consumers, the most popular stores are primarily fast food, discount retail, and pharmacy chains. There are two gas stations on the list, Shell and 7-Eleven.

The nation’s most-visited stores are popular for a range of reasons. One of the main reasons is likely the sheer size of some of these companies. With 14,155 McDonald’s restaurants and 13,429 Dollar Tree locations nationwide, the two chains are virtually ubiquitous. Similarly, Walmart, the world’s largest retailer, has enough stores in every state to be widely accessible to most Americans.
