Shoppers in the United States made about 1.6 trips to grocery stores on average per week in 2018. Surveys have shown that U.S. consumers tend to spend the most on groceries at warehouse clubs such as Costco, with an average of about 89 dollars per shopping trip. Even though online grocery shopping has existed for years, the vast majority of consumers still prefer to buy groceries in stores.
