ALDI

Aldi is one of the nation’s fastest-growing grocers. The chain focuses on low prices with a no-frills business model that claims to save shoppers up to 40% on their grocery bill.
Aldi prides itself on thrifty innovations — like its system to deposit a quarter to use a grocery cart, and then getting the quarter back when you put it back. But mostly, it’s about the thrift. The chain requires reusable bags (it sells its own) and it shelves groceries in their original shipping boxes.
