Thanks Oana. Yes, this is a global problem, it's far greater than the US supermarket numbers and not easy to put a number on. Sophisticated cart tracking systems do exist today and even services to retrieve carts, but the cost for long-range tracking is about 1/3 to 1/2 the cost of carts themselves. There has to be a way to build a better mousetrap.
