In spring 2013, in order to cut costs, Bottom Dollar started to require a quarter to use a shopping cart. When the quarter was inserted, the cart would be unlocked from the other carts. When the cart was returned, the customer was refunded their coin, effectively costing the customer only the time to return the cart. This was a practice also used by Aldi. Though ubiquitous in Europe, where both Aldi and Bottom Dollar's parent company Delhaize Group are headquartered, it is rare in American stores which often have employees return carts left in parking areas.
