Des Moines Register As Iowans on food stamps are set to receive increased benefits under a new stimulus package signed into law Dec. 27, those seeking to use their electronic benefit transfer cards to order groceries online are seeing their options grow. Aldi, in partnership with the delivery service Instacart, on Dec. 17 became the latest grocery chain to offer the service to Iowa participants in the Supplemental Nutrition Assistance Program, more commonly known as food stamps. The chain joined two large retailers, Amazon and Walmart. During the pandemic, more retailers in Iowa have joined other states in a pilot program to allow for grocery delivery and curbside pickup to participants in SNAP, an option long unavailable for them. The U.S. Centers for Disease Control and Prevention continues to recommend limiting visits to grocery stores and using online services when possible.
