thy name be buggy cup holder. If you look inside the handle on either side, the left one has no bottom for longer / wider cups and the right has a wire bottom for containers too small to wedge before falling through. Genius! ;)

And... greetings from Indiana once again. This photo taken of the buggies at the Meijer in Merrillville. And no, my country @ss has not seen a cup holder on a buggy yet. And yes, it is called a buggy.
