Here is what USPS is doing:
Free samples of CPG products, including candy and snacks, will be delivered direct to homes through a test program by the U.S. Postal Service (USPS) early next month.
Sample boxes will contain an assortment of 10 to 11 products from a range of CPG companies, it says. It will be distributed by letter carriers on a national, but limited basis in May, and in larger quantities to consumers in Charlotte, NC, and Pittsburgh, PA, the USPS says.
According to Robert Bernstock, president of mailing and shipping services, the product samples will be traced to determine whether sampling converts to sales.
Patricia Licata, senior public relations representative, says CPG companies will not be charged for their test participation, but will have to pay in the future.
