Whole Foods Market is testing click-and-collect service at a store in Plymouth Meeting, Pa., and plans to expand the test early next year to a Southern California store. If successful, online ordering could be available at all 320-plus locations. Shoppers pay a $5 fee for orders of less than $100 and no fee for orders costing more than that. Click-and-collect service is prevalent in Australia, the U.K. and several European countries. Grocers including Albertsons, Harris Teeter and Safeway also are testing the service.
