I've always hated grocery shopping - when I was a kid I was convinced it was a form of torture my parents used on me and even today, I'm much happier if I can breeze through while listening to my iPod.

For $1, parents can rent one of the carts (there are two competing manufacturers), which are built to attract the eyes of toddlers and, of course, convince parents to pay the money to satisfy their young one's desires. The big problem right now: the cost of the carts may keep grocery store chains, who traditionally do not have much of a
margin
for error in costs, from adopting the carts.
