Coffee
Most people can’t get their days started without a cup of Joe. Because coffee is relatively inexpensive, you might not question Walmart’s prices. The truth is, competitors like Amazon typically sell the same brands of coffee for less.
For example, Walmart’s price for Folgers Black Silk Dark Roast Ground Coffee (24.2 ounces) is $7.48, but the coffee sells for $6.99 on Amazon.
