Coin-controlled apparatus for locking shopping carts together in nested series at a cart parking station having coin-controlled mechanism mounted on a cart, e.g. on the handle of the cart, which is adapted for receiving and releasably locking therein a latch bar on a tether which is attached to the next cart in the nested series, requiring deposit of a coin to release the latch bar to free the cart for being wheeled away by the user, and holding the coin until the user brings the cart back to a cart parking station, nests it in the end cart at the parking station, and inserts the latch bar which is tethered to the end cart in the mechanism to lock the returned cart to the series and to provide for return of the user's coin, and a housing for a calculator at the bottom thereof, the calculator being movable from a retracted position in the housing to an extended position projecting out of the housing when the mechanism is operated to release the latch bar, and back to retracted position when the latch bar is inserted.
