Do you not like having your hands full when you leave the grocery store? I guess that can be a problem for some people, if they want to talk on the phone while walking home from the store. And if those same people don't want to use a rolling cart, there's now the Yoke, a shoulder strap that can hold your groceries for you down at your waist.

I'd worry about a half-gallon of milk banging into my leg with every step, but hey, I also don't mind just carrying my groceries, so I'm clearly not the target market here.
